GTX 480 SLI: Worth it? Need advice...

post #1 of 23
Thread Starter 
Right now I have GTX 480 and an Intel i5 2500k (4.0 GHz) CPU. The monitor is a 24" 1920x1200 native resolution.

When I play with max settings in Crysis 2, Metro 2033, and The Witcher 2 the framerate isn't that great. I didn't perform any benchmarks but I get nauseous with a lot of games and low framerate definitely doesn't help.

1) What could I expect if I purchase another GTX 480 for SLI?

2) Is it better to purchase GTX 590?

3) Will I be OK with my 2nd PCIe 2.0 slot running at 8x? (any performance loss at all? I just purchased this motherboard a little while ago and everything I read said PCIe 2.0 @ 8x is perfectly fine...)

4) Is micro-stuttering still an issue for SLI?

A massive increase,a 590 is a piece of crap,u will lose like 1 fps (which is nothing) cause of the 8x slot.

Do I need identical GTX 480 cards?

The Zotac GTX 480 AMP! is running $480 (!!!) where other GTX 480 cards seem much cheaper...

You should be ok with just OC'ing your current system further. I don't have Crysis 2 but I have Metro and Witcher 2. Witcher I run maxed out minus ubersampling and get about 50-60fps average. Metro I run on DX9 because it looks virtually identical unless you are running the DX11 advanced DOF and Tesselation, and on metro I easily clear 60fps.

Of course if you absolutely demand maximum everything in these select games, and feel it is worth the extra $200 odd dollars to be able to achieve that than go for it.

u can mix and match brands,im not sure if the amp version has a custom pcv or not but i think if it does u have to get the same one (i heard this from someone)

Much cheaper to get another 480, instead of 590. Performance is comparable.

You'll have more heat and power draw with the second 480.

8x pci 2.0 is negligible compared to 16x

No microstutter that ive seen.

You can use any brand of GTX 480 to SLI yours with.

If you want a cheap one, check out the forums. They go for $190-225 on there for reference cards, and about $50 more for non-reference coolers.

Do you currently dislike the performance you're receiving? At 1920x1200 there's not all that many games that will completely stress out a GTX 480.

For Micro-stuttering, it's been fixed for most occasions. Some people still complain about it, but the majority are fine.

EDIT:
If I max out the settings of Metro 2033 on my laptop in 1080p, I usually stay around 25-30 FPS. Your setup has a lot more power to it. What's your average frame rate?

lol - SLI 480's will equal 590's at stock speeds, and dominate a 590 when overclocked as 590's don't typically overclock well (and 480's overclock absolutely amazingly)

If its up to me, I would get the 480 as it is significantly cheaper with a much larger gain in fps, but thats just my 2 cents
