It comes with a vga and dvi onboard, but due to... something..., I can't plug anything into the dvi port. So, I'm taking that as a sign that I need a new video card. I happily took off to bestbuy.com and started looking at the video cards. That's when I noticed a little thing called wattage on the PSU. Of which, I only have 300... on a brand new machine.. grr.
Since it already has a Geforce 9100, one person I talked to was afraid there could be IRQ resource conflicts with my onboard.
I'm not married to any of these, if someone thinks a different card/psu would work better. My only constraint is that everything must come from Best Buy. I'd love to support Newegg, but they don't take BB credit cards.
Thank you, everyone, for reading this, and any help you may be able to give!
The Best Buy PSU link you provided doesn't come up with anything, but I went to the site and looked at the PSUs, and it looks like it is an older BFG. That is not a good one; see the little red voltage switch? Also to be avoided are any Dynex or Rocketfish. Both have been tested at a couple of different sites (jonnyguru and hardwaresecrets) and found to be overrated pieces of fecal matter, especially the Dynex. Any of the Antec or Corsair units would be good; even the 400W Corsair would have no trouble with a 4670 or 9600GT (or anything less).
