Hello, I have an HP computer with a 250 watt Lite on power supply (14a on +12v rail) and I want to install a video card without changing the power supply. I am looking at either an XFX ATI 4550 or XFX ATI 5570. I installed the 5570 and it worked fine, but I began having more "not responding" errors (but no crashes in games) so I took it out. The most demanding game I want is COD4 (i have a 15" monitor). Other specs: c2d 2.93, 4 gb ram, vista 64. Thanks.
All of the games worked fine, I just received "not responding" when opening Internet explorer and the downloads folder. Things seemed a little more sluggish as well. Not sure if it was due to inadequate power. Would a 4550 (XFX with fan) use less power and still run COD4 on medium (15" monitor at 1024 x 768)?
I have 4 gb of ram. I am just worried that I will kill either the gpu or the psu over time using a 5570. I wonder if a 4550 would draw a little less and be safer? I just want to play older games mostly (BF2, battlefront, BFME) and maybe COD4.
