He said under hence i put the antec 450w, the xfx 550w is better, but the antec 450w will do just fine for any 7850 or 660 gtx.
If not at that price range he can get an antec 450w +660 gtx which is better card.
The cheapest solution is an antec vp-450 and the evga 650ti, it stays bellow 200$ even without the rebates.
Or a 7850 cutting in close with rebate.
I don't know what's the monitor resolution he has, the 650 ti could be even overkill if he has a 720p monitor.
Yes, true, but the antec vp-450 is a good psu, it can deliver ~500w @45c, not some diablotek,raidmax, coolmax, cooler master psu.
Toms hardware used it on the 500$ budget pc with a 7850.
As for the card, it's the best he can find with the rest of the money, either a 650 ti or 7850.
Well, suggesting that someone save up a bit more money to end up better off....is a bit different from how the statement I quoted came across. If he's in a position to do so, saving up a bit extra would be his best option.
