I need good advice upgrading video card

[Jack.B.Nimble]

I have a gateway dx4831 i5 750 @ 2.67 GHz , and I am looking to upgrade my video card. I currently have the radeon hd 5570 , and I am interested in the 5850 but I am not sure that my computer is good enough to do this.

My psu is a (liteon) ps_6301_08a , I believe it's only 300w, I understand I will most likely have to upgrade that to around 500w.

Anyway , if I upgrade my psu will that be enough to upgrade the video card to the 5850?

btw, this is for gaming.

what are your reasons for choosing the 5850?

would you be willing to try nvidia?

what's your price range?

I'd suggest a 6850 because i was doing some reading on it and it seems that the 6850's performance is almost on par with the 5850 but it's a lot cheaper and draw less power.

I have been looking at a few different radeon cards, but the 5850 is a big jump from what I have now with out going to over board (I think).
I would consider nvidia aswell, I have just never had a nvidia card.
I would be willing to spend around $400 on a card aswell as upgrade my psu.

Do you foresee any problems with the specs of my computer upgrading to something like the 6850 besides the psu?

The only one i can think of right now is perhaps the size of the case because the 6850 (and the 5850) are both 9" long. I cant really judge the dimension of the case by the photos.

well, I guess I'll have to break out the measuring tape... it is a fairly big tower , I had it open earlier and the card in it now has tons of room to spare.

Thanks guys.
