4850 vs gts 250

i am building a new rig with the phenom II 940 processor and a 790x or 780g based mobo.

should i go for :

1. xfx 4850 gddr3 which is for $170 here in India

or

2. zotac gts 250 which is for $180.5

im planning to game at resolutions of 1650*1080

please suggest .

p.s. im not planning to crossfire.

kk thanks.

i have another problem which is whether to go for a 790 chipset mobo or a 780g 1 pcie slot is enough for me but does the 790 have any noticable improvements over the 780g??

and if i need to oc my proccy i just need to up the multiplier so should i spend more in getting a 790 based mobo???

kk thanks can u suggest me a good gigabyte atx mobo based on the 780g chipset within $100?
