Hi guys, I have an HP xw 6600 Workstation. It has a dual-socket motherboard each with Intel Xeon E5450 Clocked at 3.0 Ghz, it has 8 gigabytes of RAM. Now, I was wondering that can I use this PC for high-end gaming? Like in ultra settings/60 Fps oh and 1080p. The part that confuses me is that will this PC support high-end graphics cards like NVIDIA GTX 770 4GB and whether upgrading this PC is worth it or not? Or should I just start building a new PC from scratch?
