hi, rght now i have the NVDIA GT430 card and my system specs are:

CPU: intel core 2 duo 32-bit
PCI 2.0
RAM: 4GB.

my budget is for the ATI Radeon Power Color HD 7750.

the biggest problem is the lagging of the 60% games i play( i somehow manage to play Crysis 3 online with very low settings).

can you kindly suggest a graphic card which is suitable for my system and stops the lagging. ( kindly forgive if i used wrong terms i'm not that good in hardware).
