HD 4850 or a 4770 with this PSU

If the listed specs are close to reality it should be able to handle either card.

I am thinking of buying the 5750...Cuz of Direct X 11....But the card is like equal to 4850 in reviews....Should I get the 5750 or the 4770?

That PSU should handle those cards.Can't comment on its quality though...

5750 is faster than HD4770.

What resolution do you game at?

I only have a 17 inch so only at 1280x720......If you look in to reviews the 5750 is only a little better than the 4850 and the 4770......Is direct x 11 a good excuse to go for this instead of a 4850 or 4770?

With a rebate code, this 1gb 5750 is at 120.00, thats a good deal. I have a 4770, and it performs great. But for 20 dollars more, the 5750 has 720sp vs 640 on the 4770.

For your resolution all the cards you mentioned will do great.

I don't think you will notice much improvement (DX10 vs DX11) on a 17inch screen.
So just ignore DX11 and now decide which card you should get and how much money you wanna spend .

Are you serious?

Yes I am.

1 more thing I have a PCI E 1.0 slot I think so will there be a problem?

I really don't think a 17" screen will prevent someone from seeing the benefit of DX11 features... It's not like it's an ipod screen or something.

PCI E 1.0 slot will be fine. No worries  

Well, i was just thinking he can get some RAM for a more balanced rig. For that he can get away with a 4770/4850(Bit cheaper).

DX11 will look good but does that matters of you're gaming at 1280x720?

Ok fellas one more question is POWERCOLOR a bad option?
