IRacing Purpose Built Rig
« on: March 31, 2013, 03:37:55 AM »
So I've got a guy at work who wants a purpose built rig for this game, but I'm not all that familiar with it.  Can anyone tell me if this is about right for running it on ultra without being too much overkill?
Minimum requirements http://www.iracing.com/membership/system-requirements/
NOTE: THIS IS A PURPOSE BUILT, SINGLE GAME SYSTEM (hence the 64GB SSD).  This guy's not really a gamer, he just wants to run IRacing on max with good performance.  It's going to be hooked up via HDMI to his TV and only ever used for this one game.  He also isn't using this as a personal computer.

CPU: AMD FX-4100 Zambezi 3.6GHz (3.8GHz Turbo) Socket AM3+ 95W Quad-Core Desktop Processor FD4100WMGUSBX
VGA: SAPPHIRE 100355-1GOCL Radeon HD 7850 1GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card OC Version
RAM: CORSAIR Vengeance 8GB 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M1A1600C10
Mobo: MSI 990FXA-GD65V2 Desktop Motherboard - AMD 990FX Chipset - Socket AM3+
SSD: ADATA XPG SX900 ASX900S3-64GM-C 2.5" 64GB SATA III MLC Internal Solid State Drive (SSD)  (And an adapter for 2.5" to 3.5" so it fits in the bay)
PSU: Rosewill CAPSTONE Series CAPSTONE-650-M 650W ATX12V v2.31 & EPS12V v2.92 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply
Case: Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case, comes with Three Fans-1x Front Blue LED 120mm Fan, 1x Top 140mm Fan, 1x Rear 120mm Fan, option Fans-2x Side 120mm Fan
DVD/CD Burner added, they're like $20 now
Win7 64bit Home
Total build cost +shipping after all the savings and such is $753.86

I just want to get some feedback and see if anyone's played it and would have a good idea if this would be too much overkill to run it on ultra graphics (if it's too much, then I might as well trim the cost a little).  I'm an ATi/AMD biased builder if you didn't notice.  But usually I've found them to be best for budget builds and have been very happy with them.

Firstly, what supplier are you buying from?
What budget does he have?
Will there be overclocking?

You've put a neat machine together, but I have some niggling things jump out at me:

I think 2GB VRAM GPU would be a better option; at ultra, 1080p textures can get above 1GB mark. Also, they are recommending a 7800 series minimum, so perhaps a 7950? GHz Edition? This will double the cost of the GPU, and the 7800s are price:performance kings at the moment - however you did say "Ultra" so if he wants to play some games at ultra in a few years (is this at all possible?), I'd recommend the 7900 series.

Just a small tid-bit but a tighter timed set of ram will squeeze a bit more performance out of the rig such as these Corsair Vengence 2x4GBCL9s (9-9-9-24) over the (10-10-10-27) of the CMZ8GX3M1A1600C10s. Also, it is much better to have both ram slots filled on a channel to maximise performance (your kit is a single stick). Most mainstream mobos support dual channel, so you might as well use it! All at $1 more ;) Just RTFM as AMD sometimes don't pair the channels - the first 2 slots are grouped, not alternating slots ???

Also, I'm a little worried about the PSU. Really, you should only go for a tier 1 builder (Corsair, Seasonic... maybe Thermaltake, OCZ). It is the most critical component in the build as a poorly designed/built unit can burn out at load, have unwieldy ripple at load, and to a lesser extent, be less efficient. I have found a Corsair HX650 for $10 more, it is a Tier 1 builder and also modular which will neaten up the build and make cable management easier.

Read that again.  NVidia 7800 series or AMD x1800.  That's pretty much netbook level GPU performance, not AMD 79xx series.  Pretty much anything like a GT550ti or 7850 is gonna be WAY overkill for what the game lists.

I was kinda thinking that.  I'll see about stepping it down to a 6000 series.

I'm buying from Newegg.  Budget is more or less the least amount of money to get only iRacing to best performance (not any other game).  No overclocking.  The RAM I listed comes for free with the mobo and I was thinking that with this game, that one there that comes with the mobo should be plenty.  I agree on the PSU.  The Rosewill one looked solid, but I do TEND to favor Corsair a little more (although we had one of theirs blow out on my parents rig), both were modular (that's really all I'll buy).

Ohh ooops.. missed that! well the AMD x1800 is the minimum i.e. 30 fps at lowest settings. The 78xx could be enough for for ultra, not sure. It depends on how demanding the engine is, I would check their forums for that.

A high end 6000 would be comparable to a next-to-high end range 7000. Check if 1GB VRAM would be enough for ultra textures though!

Sounds ok on the RAM then. There's only, at max, a 5% difference b/w dual and single channel. I just saw some shots of the Capstone, it is indeed modular >.> . Honestly haven't seen these in Australia. On further inquiry they don't seem so bad. I just know the hx650 has a 7 year warranty while the capstone has a 5 year one... something else to consider.

Well neither has been made in a LONG while. I'd just get something like a GT550ti or 7770 for ~$100 or so. That way he can play other semi-modern games as well, and have late model drivers and support and all that. A slower card based on a more modern architecture will pull less power than an older equivalent card, thus putting less strain on the power supply etc.

Honesly an AMD A-10 based laptop without a discrete GPU would probably be fine here tho.

OK, so this game was released in 2009... and it RECOMMENDS an x1900 (minimum 9700 PRO). So a 7770 or 7850 should be brilliant for it! Really, an APU/i5/7 could possibly handle it. Probably....

3DMark06 scores:
Here's an x1900 scoring 5927: http://www.3dmark.com/3dm06/241987
a GT240 (What I took out of my rig 3 years or so ago) scoring 10117: http://www.3dmark.com/3dm06/16557957
a GTX460SE (took out earlier this year) scoring 17543: http://www.3dmark.com/3dm06/15387614
and my new GPU a 7870 scoring 35409: http://www.3dmark.com/3dm06/17144749

An AMD 6620G (fairly common integrated GPU) scores in the mid 8000 range. HD4000 intel scores in the mid to high 6000s. A typical 7770 gets 14000 or so.

You can get a used gts250 for $50 on ebay that'll score 16000 or so.
If you want something new a GT630 scores ~ 14000 or so and goes for $64.  Or an AMD 6670 that scores 13500 or so for $69. (all prices newegg today.)

But for this game, could modern integrated be enough? Apparently this is purpose built so if at some point he wants to dabble in some more demanding games, can a GPU be purchased later? An A10's got a 7660 onboard, might be enough.

[Edit]: And I just re-read your old posts, including the one where you suggest an A10 lol

[Edit2]: Just googled iracing+gpu and stumbled onto this and this. If you want to wring every penny out of the build, onboard will suffice. If you want ultra (possibly not full shadows) at 120fps (you'll need >60 for a racing game) a 650ti or 77xx (really AMD, 3 77xx's and 3 78xx, and GHz editions ontop of that!) will do... and just looking at newegg there's free games going with AMD cards =]

Well...The guys just told me they want 3 to 4 monitor support, soooo they pretty much just pushed it to a 7850 with 2GB and enough ports to support it (might have to crossfire em, but we'll see).  One of them is building a pod apparently to.  Thanks for the help guys.

7850 is a great value for gaming and is massively overclockable. Make sure it's 2G as there were a lot of 1G models floating around for a while. GTX660 is in the same realm, both are available for ~ $200.

You could do 3 monitors with a single 7850 (not sure if you could maintain full graphics though, its possible?) but if you wanted 4 or more you'd need another card. It also depends on the size of the monitors.

Multi-monitor on ultra? I'm assuming with AA and AF turned up? You'll need a bit more than 2GB for that, fortunately the 7970's and 680's come packed =]

He told me the other day that it is definitely going to be 3 monitors

Definitely on Ultra graphics? For 60+ fps at least one 7970 or even a Titan.
