Ok I'm new here so sorry if I'm writing in the wrong place! To the question at hand. I own a PC with a AsRock 4Core1333-eSATA2 motherboard, and a power supply of 450 W. So my question is would it be abble to run the Gigabyte ATI HD 6570 OC 1GB video card. I'm looking to upgrade my pc with out spending too much money. And I'm thinking of adding 2 plates Kingston DIMM DDR2 1 GB 800 MHz to the 2 that I already have. I don't really have an idea of what I'm doing so I need some help. Thank you!
