Alright, I plan to SLI in the future. So do I need 4 GB VGA? Or can I shave off some money with 2/3? Also does anyone know of some awesome looking cases that could hold a GTX 770 without removing driver bays? Thanks.
No you don't need 4GB unless you plan to run multiple monitors. For 770sli 750W is usually the recommended amount since the system pulls around 557W when gaming, so 750W will give you some headroom for overclocking. As for the case, how much are you looking to spend on it?
