A side note, my friends overclocked 9600GT's in SLI will a hang with a Geforce 280 (just like a GX2 does in most situations). But he is rocking a 22 inch screen (1680x1050)... so that memory buffer is no where near maxed out at that resolution. Keep in mind that drivers have become WAY more...
What? Your motherboard does not support a Core2 Quad? If that is the case you could go in either direction and spend about the same amount of money. I have a Phenom 2 940 X4 @ 3.53 GHz (with some IMC mods to make it have a way better IPC), but you still have a higher potential for performance if...
If you need 1680x1050 and you want ALL details at MAX setting (Anti-aliasing included)... you could easily get away with a single 4870 1GB or Geforce 260. If you need to game at 1920x1200 (all highest settings), you will be fine with a 4850X2 (I love mine) or a Geforce 280. The GTX295 and 4870X2...
The reason multi-gpu setups haven't scaled as well in the past is because of the lack of processor power available. For instance, if you are running Crysis with a Quadcore at 3.5 GHz and a 4870X2, then you are going to experience a processor bottleneck. Game development in the past mainly used...
In my corresponding thread at Tomshardware.com, a fellow forum member cjl posted his results at the same settings as me using an i7 965 with a 4870X2. Interesting to say the least.
My frame rates are slightly higher at 1920x1080 with 8xAA and 16AF, but I know I don't have to processor power...
Also, I am using a motherboard with PCI Express 2.0 (Double the bandwidth of PCI-E 1.1) and I can only run the slots at 8x when I have both cards installed (4850X2 in first slot and 4850 in the other). At 8x in PCI-E 2.0, my cards get the same bandwidth available to them as PCI-E 1.1 running at...
I wouldn't worry about a Multi-GPU setup. I am running a 4850x2 with a 4850 in a 3-way crossfire and it is getting sick performance and is compatible in "every" game I have tried. Its better than a 4870X2! I actually get the same GPU Score as a Geforce 295 in 3DMarks Vantage.
To be honest... I really doubt it. If so, I would think it would be within 5 percent (definitely not worth the price difference of getting a 790FX with a R750 Southbridge)
It's pretty nice to be able to put some numbers with my tweaks. The IMC definitely helps in CPU bottlenecked situations. You did notice that I ran the Phenom 2 at 3.5 with the IMC overclocked and IMC at stock clock, right? That should give you an idea of the effect...
Furthermore, the only...
Actually, this is a big helper... I have been posting this on ATI's CrossfireX forum because a trillion people are having crossfire problems. Thank you very much for the link.
