so i have ASRock FM2A68M-HD+ MoBo and i could get GTX 745 (4gb) for really cheap to replace my current GT 740. at ASRocks website they say Max. shared (graphicscard) memory is 2GB. will my pc work better with that 4gb GTX 745 or with that my current 2gb GT 740?
4GB VRam in MoBo that supports only 2GB VRam?

Basically they are the same card. The 740 has a higher ram clock rate and 8 more texture mapping units (32 vs 24) but the 745 has a higher gpu clock rate as well as more ram. Otherwise they are the same gk107 'core' found in the 750Ti but with only 384 Shaders active instead of the 640 available in the die. If this is costing you much then I would say dont waste your time and save up for the 750ti or the 950

As long as you have a 64bit version of windows, then you won't have a problem with the amount of Vram. The Asrock website is referring to the iGPU which uses your system ram.
$87 MSI 750Ti (after rebate) That should be lower priced then most 740's...
