I'm looking to upgrade the video card and the RAM.. I want to make sure they're compatible.
I'm not set on the RAM, but I would like to have 8-16GB, I currently have 4 and might just see what it is exactly and get 2 more sticks of it making it 8GB total.
I have 4 slots for RAM, 2 are open, I am using 2x2GB right now.

I really like this video card, from what people are saying its epic and I wont need an upgrade for years. Right now im using ATI Raedon 5770 HD 1GB.
Really want to get a good 2GB video card for under 300 dollars.

Keep in mind I haven't shopped around to get the lowest price for these two upgrades, but if they're compatible and you'd suggest getting them I will definitely see where I can get them cheapest.
Any input is appreciated, thank you. Let me know if you need anymore spec info.
