250 or 4850 ???

Here is my current card i am using

GPU processor: GeForce 8800 GTS
Stream processors: 96
Core clock: 560 MHz
Shader clock: 1300 MHz
Memory clock: 850 MHz (1700 MHz data rate)
Memory interface: 320-bit
Memory: 320 MB

I have been looking at getting either a 250 or a 4850 but didnt know how much of a perfomance jump it would be so which one should i get and how big would the jump be ?

Sadly i cant afford anything better and my psu woudlnt handle them anyway.

thanks

Are you running into any problems on current games? If not, I'd try waiting if it isn't urgent and saving up. Maybe in 6 months or so you'll be able to skip directly to ATI or NVidia DX11. 8800GTS to either of the above would improve a little, but probably not enough to justify the cost.

No, it's not.

ok so if you look here in the chart they reckon a 4770 is better than a 4850 ... thats why i said about it

"The Radeon HD 4770 is able to beat the HD 4830 and the Geforce 9800 GT most of the time and sometimes even get on the level of cards that are more expensive like the Radeon HD 4850 or the Geforce 9800 GTX."

The chart you're looking at includes pricing, so they're saying that the 4770 gives you a better bang for you buck. If you're looking at sheer performance, the 4850 will win.
