suggest me a graphic card for my desktop PC?decent gaming performance n ofcourse economical?

In terms of value for money, a hard to beat deal is the GTX 460 cards from NVidia. They provide good enough power for all games (new and old) at very decent graphics settings (with mine I run all the games I want at 1920 x 1080 with high settings, 4x~8x AA). They've been rated as some of the best scaling cards when it comes to multi-GPU setups and they are CHEAP for it as well. You get PhysX (GPU proccesses graphical calculations in games instead of the CPU) and very fast DRAM on a 256bit bus, making sure the card doesn't bottleneck himself for some reason. They overclock VERY well (specially the MSI cards with the Cyclone and TwinFrozr coolers fitted) to boost performance even more.

I own an MSI GTX 460 1GB Cyclone card, overclocked to 800MHz and it performs MAGNIFICENTELY. This card is a bit more expensive than the cheaper makes, but it shows (I sometimes get a GPU temperature of 24'C at idle, when the room temperature is a bit lower than normal).

40 gigs hardpersistent will slightly be adequate. when you're construction a pc that susceptible, i'd get a decrease end pictures card. bypass with nvidia. I honestly have a 9800 gtx+ and it truly works tremendously solid notwithstanding it really is going to be bottle necked by utilising your processor. i advise a 9800 gt.

Radeon HD 5770

140$ if you can afford but is the best cheapest card runs a lot of games on full! just make sure you have a good power supply for it requires 450 watts or greater.
