CPU I would recommend is the i7-4790k its the best one int eh world and is very cheap[/quote]
Why the heck does VRAM and GDDR matter that much to you? Also please don't recommend an i7 CPU together with a 750 Ti.
Ok, ok maybe he wants to play a very graphical intense game GDDR5 is the fastest VRAM. GTAV for example when your going thru the Graphical settings it will say how much VRAM is available the better, more demanding settings will raise that bar and when that bar is full and you play it will lag, but if you keep it low and adjust it, it will not lag or kill your FPS. Don't even say I know nothing from computers.
