I am looking to upgrade my comp some, for Bioshock, and believe I have found what I want. I was mainly interested in keeping this system going until May 08. When I will be done with college and have my own income, to build a new system. I was aiming to keep it under $300 as well.

My main concern is the video card. I don't have Vista and don't plan on upgrading to it on this system either. So, I was not looking at the DX10 cards. There is also some power confusion. I was looking for a card that has the same power requirement as my current one, 350W, and this one appears to. What I am not sure about is if I have the amps. My power supply says that the +12V supplies 33A but, the card mentions "with a combined 12V current rating of 22A or more." This wouldn't be such an issue if it wasn't for the no-refund policy on this card.

I am also interested if yall's opinions of my choices, if I should wait, better ideas, etc.

Thanks in advance.

Thanks for the response but, I believe mine is different from the one you linked. Yours has two +12V lines but, mine only has one. I was concerned about the combined +12V part of the amp requirement.

My single appears to have more then enough amps but, I am not sure if there would be a problem with using one +12V with enough amps instead of two +12V combined. This maybe a silly concern but, the "no refund" warranty is stopping me from just buying it and see what happens.

U can also probably get a splitter incase you do need 2x6pin adapters.
