Since your IGP is quite capable of running games at low settings and a card worth 3K won't do much better, so better stick to your current card or get hold of a second hand 8800GT or 9600GT. You could have saved 2000 by buying FSP Saga II 500W and got yourself a HD5670. Why did you buy a VX550 when you weren't getting a graphics card. It's almost the ultimate PSU for a non-SLI/xFire system.
care to explain why GTS250 isn't a better choice over HD5670?Thats not a good choice.Get Sapphire HD 5670 512 MB @ 5.3k
i knw the op asked for 3k card at firstThe final price would be over 7k.Also no DX11 and power hugry (160w).
Do you think the price difference compromises with the performance difference?
He asked for a 3k card.Thats why suggested the best card in the lowest possible budget.
There is another GTS 250 512MB DDR3 from palit @ 6.2k.Dont know its worth for the performance increase.
i agree with Ajai in this oneI wont recommend a GTS 250 @ 7k.
Its an old card.Its 65nm technology,power hungry,produces more heat,no Directx 11,no DDR5,Shader model 4 etc..
If your max budget is 7k.Then go for Sapphire HD 5750 @ 7.2k It has all the new technologies and also powerful like GTS 250.
But the best choice would be HD 5770 @ 8.5k.
