Update to Nvidia GeForce 9400 GT

Depends on the rest of the PC. Take a look at this http://www.tomshardware.com/forum/290969-33-advice-choo... add in info you are missing to your post.

I recently updated my PC to this :-
Case
Cooler Master CM 690 II Plus
*3 Fans *Mid-Tower Cabinet
*2 USB2.0 *8 Expansion Ports

Processor
Intel 3.3 Ghz Core i5-2500K Processor
3.3GHz ClockSpeed with 3.7GHz Turbo

Motherboard
Asus P8H67-V Motherboard
ATX Form, Intel H67, 1155

RAM
G.Skill RipJawsX DDR3 8GB
2X4GB PC RAM, DDR3 1600Mhz


Hard Disk
Seagate Barracuda 1TB HDD
3.5in, 6GBPS, 7200RPM

Optical Drive
LG GH22LS90 Optical Drive(Black)
48x CD, 22x DVD

Power Supply
Corsair CMPSU 650W
650W power

With that system, any of the low to mid range cards from here http://www.tomshardware.com/reviews/gaming-graphics-car... will do the trick. You can run a pretty big card on that power supply, but the i5 will hold it back a bit, so no need to go over mid-range.

At this point pretty much any card you go to will be a solid step up. If you spend in the $140 range and get
a 6850 you are talking about multiplying the performance of your current card many times over.

That is the most ridiculous thing I have ever heard, the i5 will NOT be held back by 99% of cards.

the sapphire radeon hd 6850 looks good right??

The i5 is one of the best CPUs right now, how is it going to hold him back?

even i think the i5 2500k is currently one of the leading cpus for multimedia and gaming purposes.. thats y i went for it..

The most important question is what is your budget and at resolution you want to play the games.
