I suspect you're playing on fairly low settings. What brand and model (not just wattage) is that PSU? If you review the gaming CPU and GPU charts, you'll see that what you have is fairly low on the pecking orders. Still, it illustrates quite nicely that it doesn't take thousands to build a PC to play games.
A HD6770, HD6850, or GTX460 would all be strong upgrades for you, and will run on your PSU (assuming it's not something like a Diablotek or Apevia). Even the last two may be bottlenecked some by your CPU, so anything stronger would be a waste.
ok , all im really trying to do is boost the graphics in the computer i know it needs to be upgraded but im giveing it to my 10yr old son and im building or buying a new one not sure the whole research of part is confuseing, not installing and getting it to work, its the whole i hope i dont buy a pos part and have to upgade asap or buy something differant... it just scares me, money is tight and the only time i can do big$$ as in ($0-$1500) on a new rig, not every year buy every 4-5 yrs so im just confused
but just to let you know, beleve it or not i run it at 1024x786 on custom medium with some on low .... i just know i can pull bett out of this old machine before i give it to my son...

Ok, that PSU doesn't look great (without active PFC, it's an obsolete, inefficient design, and no doubt overrated), but it should certainly be strong enough for a HD6770. That would probably be a decent match for your CPU, even if you later up the resolution, perhaps to 1368x768 or even 1400x900.
check this out would it be worth a try, if i buy a card off ebay that has display issuse(lets say a 8800gtx) and use that as a physx card because i cant use the display do u think that could work (note) i can get thoes cards for like 30-60 on ebay all day but i am looking for a better card than the gt520....
A GTX550Ti is similar in power to a HD6770; weaker, but similar.
I would not buy a card with "issues;" who knows what else may be affected? Few games use PhysX; the effects are nice, but IMHO I don't think it is worth buying a separate card just to get them.
