I am planning to upgrade my system to increase gaming performance:
CPU: AMD Athlon II x3 435 (triple core 2,Ghz) although I am not intersted in changing it CPU right now
Motherboard: Asrock N-68S
GPU: XFX Radeon HD 4770
Power supply: 550W with 2x 6-pin PCI-e Connectors (I do not know the name)
RAM: 2x Kingston 1GB DDR2 RAM
To be brief I am currently trying to decide between 4770 CF and 5850 But there is a problem:
my motherboard is not crossfireX compactibe, so I am going for the 477 CF I`ll have to change motherboard. I could get an MSI 790XT-G45 for about 100$. If I go for the 5850 I won`t need a new motherboard at all and I would get DX11, but I really need those 2 extra RAM slots plus some other features and extension slots that my current motherboard does not have.
Price of 4770 + new motherboard should be about 210 $
Price of a single 5850 would be 300 $
The performance of 2x4770 should be almost equal to a 5850. If I go for with the CF 4770 I will save some money and increase RAM and I get a CrossFireX compactible motherboard
By the way, my monitor does not support resolutions higher than 1280x1024
