Upgrading gfx card hmm

[blu_ey]

Hi i want to upgrade my gfx card but i dunno if my current power supply will hold a powerfuller card.

This is my system specs
p35c-ds3r
4gb 800mhz
q6600 quad core
550watt
current card connect3d ati radeon x1950xt

I was wondering which is the best power supply to get for price wise

and which is the best gfx card between £80 - 150

Anyhelp much apreciated

whats your budget for a PSU?

550W is powerful enough for all of today's high powered video cards.

The HD 4850 is about the best you can get in that price range. This would be a nice choice: Sapphire HD 4850 512MB GDDR3 Dual DVI TV Out PCI-E Graphics Card - Ebuyer

well depends on the amps on 12V as I have seen some 500+W that aren't exactly up to snuff with that.

but for most cards in that price range, if the amps on 12V are enough, then it should work fine for a single card setup
