PSU - 300W (Ill upgrade it depending the Video Card)
Actual GPU - Geforce gt 240 512 mb GDDR5 OC at (640Core/2000Memory Bw)
And ill play in my Samsung 32" Full-HD

So my goal is to play at 1920x1080p

My budget is around $250-$350 for both GPU and PSU

A GTX 460 1 Gb would be a great choice. Get a nice 600 watt or greater PSU from a reputable brand and it should fit nicely into your budget. Stay away from 460's with an SE designation.

Having said that... Once you get the 460 installed you might find that your CPU is bottlenecking your system in some games.

A quality 400W-450W PSU will be enough for a HD6850, which has a single PCIE power connector. A 1GB GTX460 (non-SE) has two; you can use an adapter, but there are a few reasons why I think that is probably a bad idea.

Given the age of the base system, it might be worth it to buy the PSU based on the next build's requirement; if next build is 1-1.5 years away, a 650-750W PSU would be nice.

That's true; if these parts will be transferred to the next build, a 550W-650W PSU and a HD6870 or GTX560 (if you can find the two within your budget) would probably be a better choice.
