Hi, i want to upgrade my GPU from HD 3650 to GTX 770 for my old LGA 775 Xeon PC. I've found it cheap with full-box content. I'll probably get shocked from the performance difference. I've heard the 2GB VRAM not enough for modern titles. I'll use this GPU for gaming and editing software at 1280x1024 resolution. I've also found R9 280X but i'm not sure which model is better. Thanks.
