Hi, I'm looking to buy a graphics card for a fairly old computer of mine. The specs are:
ASUS P5LD2-VM motherboard with one PCIe slot
2GB DDR2 RAM
Intel Pentium 4 3.2GHZ
APEX AL-B500E 500W PSU (20A +12V Rail)
Onboard graphics (currently)
Windows XP
Ideally, I'd be able to squeeze a couple more years out of this system by adding a new graphics card. I'd like to be able to play games like Portal 2, and just possibly GTA IV. I'm looking at cards ranging from a 4670 to a 5770. The money, at least in this range, is not an issue. However, I'm wondering if, because of the limits of my system, there will be a point at which the other parts of my computer bottleneck the card to a point where it isn't worth having a better card. What do you guys think, is it worth getting a 5770, or would I be throwing my money away because of bottlenecks?
