New Video Card and PSU

**hannibal** · 01-01-12, 08:48 PM

So its that time o'year again and I am going to upgrade my video card and PSU. The PSU because I have had the same one for three years and its time. The Video card because of this:

http://developer.amd.com/sdks/amdapp..._Developer.pdf

It would appear that AMD wants me to use OpenCL from now on so, fuck them, I am going (back) to CUDA. So the question is, for games at 1280x1024, gtx 580 or 560 ti SLI?

Wait...I JUST bought an ATi card, and NOW you're going Nvidia? *grumble grumble*

SLI usually is more effective at higher resolutions and not lower resolutions. Maybe a 570 with 1.5 GB or more memory instead? I'm not sure you'll get the money out of the 560SLI or 580 at that resolution. If you're going 1920+ later, maybe the 580?

I have a 570 and can play BF3 on high/ultra at 1680 with framerates that don't dip below 55 and are usually around 75-85 and go over 100 on certain maps.

I am going with the 580, the reason is Folding + Research.

The 580 is overkill for the 1280x1024 res. The GTX 560ti is still great at folding.

I need the 580 for research, since I need to write programs that optimally preach resources to all 512 cuda cores, then when I put them on 590's in the production environment hopefully it will scale across the GPUs. I just cannot believe how monumentally AMD screwed me by discontinuing CAL, I mean it would be okay if the AMD implementation of OpenCL in the APP SDK didn't suck massive donkey balls.
