Hello everybody, I'd like to get some advice on picking out a graphics card. I run an older Core 2 Duo running at 2.5GHZ, so I'm wondering what would be the best graphics card I can buy without too much of a bottleneck. I'm thinking of either the Radeon HD 7750 or 7770, but what are your thoughts? I plan to use this on a monitor with a native resolution of 1280x1024. Thanks.

Would it be worth the extra money if I upgraded from my current 425W PSU and went for the 7770 instead, assuming I upgrade the rest of my computer later down the road?

It's an old no-name power supply, not too sure who the manufacturer is.

There are 20 amps on my +12V, but upon inspection it seems I can only pull out a max of 205 watts off of this rail. Will this be enough to power a card like the 7770?
