Vidoe card advice

[Captain@Lake]

Trying to decide which is best and significant performer considering cost over either one?

NVIDIA® GeForce® GT 620 1GB DDR3

NVIDIA® GeForce® GT 640 1GB GDDR5

AMD Radeon™ HD 7570 1GB GDDR5

thanx

Is the 7750 out of your budget? It costs the same as the 640 usually but performs like the 650

Out of the 3 I would pick the 7570 (rebadged 6570 with GDDR3/5)
