I am about to build a budget pc for gaming (just need to get some money first), and I was considering Gigabyte GTX 750 ti 4gb OC for my build, but I noticed that MSI GTX 950 2gb is about the same price. Do the +2gb make a difference, and is there a catch. GTX 950 Spec wise is better, and gives more fps than 750 Ti 2gb (around +5-10 FPS). I want to build a some what future proof PC, but I am low on budget. Around 500$ max (around 250$ for graphics).
