can a dual core processor run 4gb graphic card
Please help. I have asrock g31- m motherboard with dual core processor and 4gb ram. I want to buy a 4gb graphic card for better performance gaming.
A 4gb vid card isnt going to perform like you want it to with that setup. Anything more powerful than a 7750 is going to bottleneck and even that may too. VRAM on a vid card only matters if you have the hardware to run it and it isnt a crap video card like a 630 or 640 or something like that.
STACKS ON DECK said:ram should be upgraded to 8gb and and the processor will bottleneck the latest cards 660 and above
Absolutely right, a dual-core processor will bottleneck a 4GB GPU. Performance of a GPU is relative to the clock speed (and more recently, cores) of your processor. Having a dual-core or slow quad-core won't allow the GPU to perform at its best.
More GPU RAM doesn't mean it will perform better. GPU RAM is used primarily for post-process rendering, such as anti-aisling, or for gaming across multiple monitors. 2GB is more than sufficient for the vast majority of games on the market. The performance of a GPU is measured in RAM, bus speed, clock speed, stream processors and a host of other things.
In summary, yes a 4GB GPU will work just fine, but unless you upgrade to a fast quad-core processor and 8GB RAM, you won't see the card's full potential. It's far more important to have a balanced build for gaming, rather than buying a single exceptional component.
