which graphics card to choose?

[0mg_1ts_m3]

i'll mostly be playing tf2, css, cod4, etc. at 1680x1050.

so which one of these cards would be better and could you explain why? which one will run better at higher resolution? which will run better on higher detail? if the 4850 is better, is the performance really going to make a difference?
by the way, i'm setting these up with an athlon 64 x2 5600+ 2.8ghz and 2gb of ram.

jsut bought this card, i can't even seem to OC it to the asus clocks -__-

but yeah 4850>9800gtx

so an asus OC 4850 should do pretty well against that 9800gtx =]

4850 is slightly better the 9800gtx.
the 4850 does better at higher resolution because of the newer efficient architect. it also handles aa better.
