Hello my first post here ever!! (yay) , anyway i have a PC buid with i7 3770k 8 GB of ram and 7850 radeon 2GB and I'm kinda concerned for my GPU, I'm starting to suspect it's bottle necking my i7 in gaming and is becoming outdated. Should i consider upgrading now, or hold out. My choices of replacement would be 970 GTX or radeon 300 series, but I'm worried about 3.5 thing in 970. Might also consider throwing in another 8GB stick
