and i ran an x1300 video card on my dell which had a 240w power supply. it ran perfect. although i never played games on it. but i did watch a lot of video across multiple tabs. lol
I'm not sure why you are recommending the GT 220 if you are talking about the Radeon X1300.
Anyway, the GT 220 is weaker than the HD 5550, so it would be logical that it is also slower than the HD 5570. The GT 220 also uses a little more power than the HD 5570 under typical gaming conditions. See following review for benchmarks and power consumption.
^ agreed, the 5570 only uses like 18w by itself. Either way, it would be in the OP's best interest to remove that bestec psu and get something better as it will only blow up later down the track possibly taking out other components with it.
well im just mentioning that i had a video card in a computer with a weak powersupply. and the gt220 was the cheapest thing i saw when i posted.
and yeah bestec power supplies are ultra weak sauce, if they fail they will take the motherboard with it. something like a raidmax or rosewill powersupply should be better than the bestec.
Saying that raidmax or Rosewill is better than a bestec is kind of like saying bottled water is wetter than tap water. I would recommend something from Corsair, Seasonic, Antec, PCP&C, or Enermax. Don't cheap out on the power supply! It's the only component that if it fails, can take out EVERY other component in your PC.
sure the raidmax psu arent as efficient as the corsair, and what not but at least the raidmax psu's have a resistor that will help prevent your motherboard from fry if it does fail unlike the bestec. (well at least the raidmax psu's ive taken apart [yes really dangerous i know] had the resistor)
of course antec does make really good psu's that are also pretty cheap.
and i prefer the filtered tap water from my fridge better than bottled water. irrelevant i know.
