Purchase date: Somewhere between now, and end of next month. I'm trying to watch for deals and order parts when websites have a component for some bucks off.
Budget range: I can be flexible on this, but $270ish is about the most I'd want to go.
Usage: I play TF2, Left 4 dead series, Bioshock series on a 1920 x 1080 monitor but also have a second 1280 x 1024 monitor that I browse the web or run a virtual machine on while in game. I'm also interested in going to a 3 monitor setup in the future.
Current GPU: Right now I'm currently running a Sapphire 4870 with a Xigmatek 750 watt PSU. This is on my AMD Phenom build which will cease to exist in the near future once I have all of the components for my Intel build.
You might want to wait for the HD 7850/7870 - set to be released next week. Should be in the $270 range. Very low power consumption and they have the new GCN architecture (better for DX11 games than anything else on the market).
Thanks for the input everyone. Hopefully I can wait this out. I order the Mobo and memory today when I didn't even plan on that until at least next week. I'll probably order the water cooler for the CPU next week and leave the video card for the week after or possibly 2.
