My comp is pretty much old,dont flame or troll just ty to comment or say something.

Dxdiag specs:
Processor: Intel(R) Pentium(R) Dual CPU E2140 @ 1.60GHz (2 CPUs), ~1.6GHz
Memory: 3070MB RAM
Page File: 1476MB used, 4891MB available
Card name: NVIDIA GeForce 9500 GT
My comps memorys also little.... 60gb :/ only about 1-5gb left >.>
************************************************** *******
Just found out that a dual core with "intel pentium" behind it runs worse than just dual core.

So which to buy?
Quad core~2.66GHz
or
Nvidia 250gts
Or waste em all on games that i cant run that good.
************************************************** *******
They are close to the same price range so any suggestions to which i should buy?

Adding more:
Only problem is if i buy gts-250 what would i do with my old card and would my system bottle neck the card?
