Hi, I'm Adam. I'm wondering If this graphic CARD right here: MSI GeForce GTX 750 2GB PhysX CUDA, Is better than this: Nvidia Geforce GTX 580?I'd AVOID MSI and get that card from EVGA, XFX, or some other brand including PNY as being trusted more than MSI.

The 750GTX is better than that 580GTX as shown here: http://gpuboss.com/gpus/GeForce-GTX-750-Ti-vs-GeForce-GTX-580

Although its interesting that this site shows the 750GTX being better in all specs,and then at the bottom of the page they seem to have it coded incorrectly to where the 580 and 750 benchmark results are inversed when comparing stats that are correct to the bar graph at bottom of page.Try Anandtech for GPU comparisons...How about This one? https://www.komplett.no/zotac-geforce-gt-740-2gb-physx-cuda/817124 (Is this any good?) And This one https://www.komplett.no/zotac-geforce-gt-730-4gb-physx-cuda/822439And Also theese: https://www.komplett.no/gainward-geforce-gt-720-2gb-physx-cuda/823040 and  https://www.komplett.no/asus-geforce-gt-720-2gb-silent-physx/823180.

I just want to know which are the best here.Well, the 720, 730 and 740 are low end cards so are significantly worse than the 750ti.

The 750ti and 580 are pretty close in terms of PERFORMANCE, the 580 being possibly slightly better.  However, the 580 is a much older card and will use significantly more power than a 750ti.Just please TELL me, Which One of them are the best?Personally I would go for the 750ti, the 580 is getting a bit old nowadays.Im talking about the other graphic cards. I posted link. Are they any better than 580?As I stated, the other cards you posted are all worse than the 750ti and therefore the 580.  What are you trying to do here ANYWAY?
