This may be a quick question. I am sure there are more threads in the forum but did not particularly find the one with the configuration I am about to try.
I have one HIS HD 5850 (1GB) iCooler V card. If I add another Sapphire HD 5870 (2GB) card and crossfire them together, can someone give me a rough percentage increase in FPS in percentage of games? The games I typically tend to play -
a) Action Games similar to Call of Duty, Black Ops
b) MAFIA II, GTA etc. in third person strategy.
c) FIFA 11, Need for Speed Hot Pursuit, in simulations.
I know this may not be accurate, but I am only looking for something like say "you will see about 20% rise in FPS in about 80% games you play with this crossfire".
Excellent, but not very relevant to the discussion. My initial question was only to see if pairing a 2gb 5870 with 1gb 5850 was possible and of any benefit.
After I got a no-go for that question, my only question was to the person giving me suggestion to buy another 5850 to crossfire with my existing one (both 1gb) over using just a single 2GB 5870, for the reasoning behind that suggestion. That's it
I am well aware of cross fire performances when two identical cards are concerned. I hear your point that two lower end cards together can outperform a higher end card. But since memories here were different (2 x 1GB) vs (1 x 2GB), I wanted some clarification.
Thanks to you though for your responses. Learning something new everyday.
