Okay, i just realised that i initially wanted this block but confused on the way with the gpu question and everything. So now with this card you suggested, i can now do it. Im very thankful, huge thanks. I also finally got the '670-680 PCB thingy' so you been very useful. I will think about the 4gb as this isnt my main rig, but i will see.
Once again, thank you very much!
the price difference between those 2 waterblocks are very low as well.
Also you are doing a smart thing on getting a 670 that is on a 680 PCB.
670s with 670 PCBs are good too of course but the 680 PCB is better.
Again 4GB wont benefit your system at all with 1080p resolution. If you will get a 27 inch screen but still keep it at 1080p resoluttion, 2GB will be just fine.
But again noone can be 100% sure on what the future will bring.
Enjoy your setup.
