Best recommened Graphics card

[Argonaut110]

Thanks for your advice, I think that card looks very good and right for me. To prevent me yet again finding another card tommorrow, I'll favourite that site and leave it. Btw, I didn't catch a few of your abbriations, so i'll list the ones I didn't understand:
C2Q
C2D
TDP

I don't know the CPU yet and it could very well be upgraded since I don't know what it is...but once the graphics card is purchased I'll have to wait for some money to buy a new PSU, then a new CPU unless I overclock it somehow (Idk how to do that).
But it was a case of "here's a new machine for YOU to have which you can upgrade if you need to" as previously I had to share a computer that I wasn't allowed to upgrade..
Also will this card fit into my machine?
(Going to be offline for awhile but I will come back, just don't expect a response immediately)
