i know one is laptop one is desktop and different brands
but can anyone tell me how the
3GB GDDR5 NVIDIA® GeForce® GTX 770M w/NVIDIA® Optimus™ Technology
stacks up against the
AMD Radeon HD 7970 3GB GDDR5 16X PCIe 3.0 Video Card
my old desk top has the latter .. so it will give me a point of reference
thanks in advance
