Hi,i need new video card,but i cannot decide.I`m using 19" LCD. i would like 1gb for GTA IV and other games to run good.I have read that 4770 clocks well and 4850 is bit old by now.Im going to buy used card.Going to change processor later.
Right now i have:
X2 +4200 @ 2.5
You probably won't get your MIR back half the time, so don't rely on MIRs. Just get a 4850 - it's a good card. It may old, but it outperforms the 4770, equals the GTS250 and costs less than the GTS250.
You can get a used 4850 for ~$80
If you want to go the Nvidia route, go for the GTS250 and hope the rebate company doesn't suck.
Probably. nVidia states a requirement of 450W, but these requirements are usually worst case scenario, because they have no idea what other components you have. With just one hard drive and a processor that's not too power hungry, your PSU should be fine. It will deliver 18A per 12V rail, which should be fine if balanced right.
