i recently built my very first PC a week ago successfully (was on a budge $385) and got myself the radeon 4670. now that i know how far i can push the video card (crysis), i was wondering whats the next best thing for an upgrade for around or less than $100 with my specs.
BIOSTAR A770E3 AM3 AMD 770 ATX AMD Motherboard
AMD Athlon II X4 635 Propus 2.9GHz Quad-Core
Windows 7 Ultimate 32bit
G.SKILL NS 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333
Hitachi 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s
Radeon HD 4670 1GB 128-bit DDR3
Mostly im using this for rendering videos and getting into gaming again (waiting on Crysis 2 ). been reading up on GDDR5 but dont really know if its worth getting into or just sticking to a GDDR3. Thank u for any advice that can be given.
