I recently build a new PC and I was wondering if I should buy a second 9800GTX (199$) or step up to a gtx 260 (would cost me 200 + shipping).
I play at 1280x1024 and I was wondering if at that resolution SLI would even help me (and by how much) in games like crysis since I saw that the biggest performance increase of SLI is at very high resolutions.
I know the PSU is kinda low and will most likely not be enough, even though i only have 1 HDD. I got it since i found a really good deal on it and need one for an older rig anyway so upgrading to a 700W or so shouldn't be a problem.
My main problem is if SLI increases performance at lower resolutions or just at 1680 +
Keep in mind the benchmarks for one and two cards are from different places, with different CPUs and other settings. No guarantees you'll see an improvement like 18 to 44. You might get less. Still, I think the SLI would help at your resolution too.
I agree. I'd hang on to the 9800gtx, atleast for now. The gtx 260 doesn't yet look like it's worth 200$ more than the 9800gtx. Especially with drivers that aren't yet mature.
I would also argue that the best performance increase at high resolutions comes from the availability of more vram in your system, not sli. Sli should make it easier for you to use things like AA and AF though (Crysis is an exception, cause it's a beast)! I wouldn't consider 1280x1024 to be a high resolution though, and the 512mb of vram you currently have should be able to swing any game at that resolution. Crysis is an exception, no matter what kind of setup you have right now.
I'm currently running a water-cooled 8800gts 512mb @ 750mhz and getting a 15,000 3dmark06 score. Everything runs great, but at higher resolutions (1680 x 1050 and above) things can still stutter a bit when high resolution textures come into play. So i guess my advice to you is to stick with your current card for a while, especially since you're not gaming at ultra-high resolutions.
You could also spend that 200$ (plus 30$ more, give or take) and get a waterblock for your 9800gtx:
So for roughly the same amount of money, you could overclock your card, your cpu, and have a more silent system. I guess another option would be to sell your card on ebay, and spend an extra 150$ on an hd 3870 But is sounds like you've got an sli board, and want to remain open to the idea of using it.
thx so much thats exactly what i was looking for. Right now with my E8400 and 4 gigs ram @ 1066 i get around 36 fps on high. If as looking at the benchmark i get even only close to 50 thats still a very nice increase in fps.
I know the PSU is kinda low and will most likely not be enough
You know that sound that people make when they are kicked really hard in the nutz?? I just made that when I saw your PSU. A tier 5 do not recommended in a high(er) end gaming machine
What ever you decide to do you should really get a beefier PSU.
If you really need more power, SLI with your current card will give you much more power than even the GTX 280. Seeing as SLIed 8800GT's can beat it in most situations and the GX2 is basically 2 of your cards with the clocks turned down you should have a very powerful system.
That being said...
There is only one game that should be giving you trouble at your resolution. Crysis. Unless you upgrade your monitor stick with what you have for now. Not really worth dumping $200 into your rig for a few extra FPS in one game.
As my flat is only 4 meters square I really like a quiet machine. I also want to keep top notch cooling in my system. Enter massive overkill of low speed fans! Well it gives me no direct performance gains, it is the single best upgrade I have ever done. You don't know what you are missing until you can't tell if your system is on or off when it is just a meter or so from your head
