Strange op ignoring my bios post. Check what mobo bios u have. If u have to update it, do it then come here, as these new cards wont work until u have.
Mess it up and its a new mobo on the bill also.
I'm really not wanting to go down the route of upgrading my CPU, PSU and possibly even the motherboard, especially as the monitor itself will won't be cheap!
So it looks like my best option is to ramp up the frequency on my 2500k and go for either the 970 or R9 290.
Given this route, which would be better suited for gaming at 1440p, ideally without needing a PSU upgrade? (and assuming that my motherboard bios updates OK further to Lemin's advice above!!)
290 for the vram,970 for the power draw.
Your call.
1st reply tells you why, bigger monitor likes more vram. Its perfect for up to 24". I got a gtx 970 cos im happy with my 24" monitor. Have you not looked in gfx card section ?......
