Hello! So i have a question for updating with a small budget
Motherboard: Asus P5Q-E
Processor: Intel Core 2 Quad Q8400 @ 2.66 ghz
Graphics card: ATI HD 4890
I would like to update the computers performance with a small budget, and i would like to buy another HD 4890 for crossfire, but the motherboard supports only pci-e 8x in crossfire, so should i update something else or just go for the crossfire?
I found this:
HD 4890 = 975mhz (quad piped - 3.9 GB/s data rate) = 3.9 GB/s total data rate
HD 4870 X2 = 900mhz (quad piped - 3.6 GB/s data rate)(times 2) = 7.2 GB/s total data rate
So as you can see, the 4870 X2 will be hurt in an 8X condition and why the 3870, 4650, 4670, 4770, 4830, 4850, 4870, 4890, and 4850 X2 will not be hurt in performance at all.
