what should be the last video card to my system?

You haven't told us your price range.
But that being said, for about $290 you could get a Geforce 7800GT. For $140 you could get a Geforce 7600GT.

Edited because of the move.

Its all cool. Just remember to look before you post.
What games do you want to play? The 7600GT is pretty sufficient for most games.
Its a pretty good stop gap card till you buy a DX10 card up upgrade your entire system.

yeah i know it wierd but i just found some article about in game( http://www.xbitlabs.com/articles/c [...] ames2.html ) i know this article is very out dated but the game and os still what we use now
and it said that most game today is base of the power of video card and i just thought if i buy now a video card which is sm 3.0 while a few week from now a new video card will support sm 4. then i thought maybe it worth to wait and i just wonder if it will really fitted to this kind of system which i have now

my psu is 500watt that what the store said but when i open it up it was written 480watt.. but i guess this is enough to handle..

but still can a single processor like mine can handle this kind of video card and can perform to its level?

Agree with Locky and DSN. Pick up a 7600GT and start saving up for a new system down the road. That 7600 should hold you over until mid next year until future software comes out.

The 7600 GT is a great buy, but the 7800 GT is one of the worst cards money can buy at this time.

If you can afford ~$200, the X1900 GT is great, cheaper than the 7800 GT, and faster too. Even faster than the new 7900 GS.

X1650 XT in the shops?

Are you sure you're not thinking X1650 PRO (which is a rebadged X1600 XT)?

thnx for the info guys actually i only use the integrated video in my mobo. hoping that if my rig can still keep up to this up coming video card then i rather save this money. and maybe a bigger chance that my rig will have a life span about 2 yrs.(Which can still play up coming games) enough time to buy a new rig. and maybe 2 yrs. is enough that all hardware and software is more mature and of course cheaper.


and guys 7600GT is the best budget video card in the market today right?? but i see sum product line Inno3D 7600GST which using DRR3 and it much cheaper. compare with 7600GT which is much more better in price/performance?
