I was looking into upgrading my current 8800gts 512 sli setup to the 470gtx. I was wondering if anyone knows if I would see enough improvement to justify the purchase. Would it be a dramatic increase? I'm kinda on the fence about it.
My current setup is:
Cpu: Intel Core 2 Quad Q9550, 3400 MHZ
Mobo: EVGA 132-YW-E178-A1 nForce 780i SLI FTW
Mem: 8gb Corsair XMS2 pc8500 5-5-15
Video: Evga NVIDIA GeForce 8800 GTS 512 in sli
HDD: 2x WD 500gb in raid 0
PSU: PC Power & Cooling Silencer 750
Case: Lian Li PC60B
Yea, the games aren't really struggling but some of the newer games I really can't bump up the detail as high as I would like. for instance starcraft 2. I would like to run at ultra settings at 1920x1080 with great framerates. My current setup runs it on high at the resolution but sometimes I do get a bit of stuttering.
Two 8800GTS cards in SLI is only a little slower than two GTS 250s in SLI. Knowing that you're not going to see a huge increase by going to a GTX 470 except in the cases where your two 8800 cards run out of memory due to their 512MB. Overall it would be a significant increase, but not a dramatic one. You would certainly get less stuttering and smoother gameplay though. If you can afford it go for it. I think two GTX 460s would be a better option though and you should be able to run them on that PSU.
I made the jump from the 2 8800 512's in sli to a 470gtx. Once the price of the 470 dropped to the $250 range I knew it was time to pull the trigger. I have to say I couldnt be happier. My scores went up quite a bit in 3dmark vantage and all my games run at 1920x1080 high settings with ease. I already did an overclock of 690/1380/1790 to the core/shader/mem. I tried to go a bit higher but I was getting artifacts at higher clock speeds.
These are my 3dmark vantage scores before and after:
