Hi guys, I'm planning to upgrade my graphics card (I recently have the XFX 9800GTX+). So I want to buy one of these cards: XFX GTX275 or Sapphire ATI 4890. Which one should I get do you think? Also I have a PSU of Antec Earthwatts 650W so can this PSU handle those other two cards that I mentioned? here are the specifications of my rig:

Windows 7 RC 64bit, Intel Core2Quad Q9550 2,83GHz, 4GB DDR2 Kingston HyperX 1066MHz, 2x 500GB Seagate HDD, Nvidia XFX 9800GTX+, Antec Earthwatts 650W PSU,Logitech G15 and G9, Samsung T220 monitor.

Apples and Oranges, both good cards. Why no the GTX 295? I assume you're talking about the 2gb versions of both cards?

I'd imagine that 650w would be enough for each of those, providing you're not intending to the SLI or Crossfire route, then you'd probably roast the thing.

No need to upgrade if you already got a 9800GTX+, what resolution do you game at? BTW a 650W PSU is more than enough.
