Worth upgrading for gaming?

[nitram100]

Hey guys,

I have an old Athlon x2 5200+ and a Sapphire 4830 512mb, with 2gb of system ram. I was thinking about buying a new motherboard and the 955 Phenom II, would i see much of a frame rate increase?

Thanks a lot for any help,

Sorry guys for not giving enough info the first time around! Also, thanks a lot for the replies

My budget is about £350 for a new motherboard, cpu and ram.

The games i play are Left 4 Dead 2, Shattered Horizon, COD4, Oblivion, Dragon Age and would like to play BFMC2 when it comes out.

I play on a 19" viewsonic lcd at 1440x900 resolution, i never use AA.

I would like roughly a 15% increase in frame rate with the upgrade and then buy a 5850 when they are more readily available.

Thanks a lot fellas!
