I am mostly a console gamer and I haven't upgraded the PC I build in 2012 till now (moved to an alienware laptop which I solely use for App Development and College Work). I have like 500-600 usd to spare. And I was thinking of getting a RTX 2070. Now I could use an Alienware Amplifier but I was thinking why not slowly upgrade my PC. Current Configuration : Core i7 2600K, 8GB RAM, GTX 680, MSI H67MA E45(this is the biggest problem in my setup afaik), Corsair 750W power supply. Will I have to upgrade everything or can I just swap out GTX 680 with RTX 2070? I obviously plan to upgrade it completely but right now I can only get just the RTX 2070. If not, I will just use a graphics amplifier.
