Maybe this doesn't belong here, but i have to ask someone Hello, i have a small question, for whom might know. I want to buy a new video card, i have now a hd4650 and its getting old, and i want to buy something like a Sapphire Radeon HD6570 Ultimate 1GB DDR3 128-bit , or a GT440 1GB DDR3 128-bit or something near, don't know yet, my question is, will the power source hold it, or do i have to buy a new one On the power source, its say's, Delux ATX 450 w P4, but i know that not all power source's give that output. Also, i heard that you can find out the output, by doing the math by multiplaying the Volts whit the Ampers (don't know if i wrote them corectly|). On mine it say's: +5 V -5 V 12 V -12 V 3 V +5 V SB 30 A 0.5 A 18 A 0.8 A 20 A 1.55 A Also, my other componets are: motherbord:Biostar G31D-M7 (i know, its crappy, i bought the computer 2 years ago, i was in college, couldn't afford more) RAM: 4 GB DDR2 at 800 MHz Hard disk: 500 GB at 7200 RPM video card: ati hd4650 512 mb 128 biti. I know i should just buy a new computer, but till next summer or so i'm stuck and i'm doing ok whit this one, just the video card is just old and acting up Thx in advance.
