SAPPHIRE 100245L Radeon HD 4850 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready CrossFire Supported Video Card - Retail
I'm planning on eventually buying a second one of these to Crossfire, probably whenever I get a second monitor, but money's a little tight so I think I'm going to hold off. Do I need to do anything in order to add the second graphics card, or will it be recognized as soon as I add it? Also, do I need anything to link the 2 cards?
I honestly have no idea what I'm looking for as far as power supply or case, so any help there would be appreciated.
As far as overclocking goes, is that something I'm able to do with stock cooling? I know I won't get great speeds, but I'd like to bump it up a little bit. Does that motherboard work well for it? Also, is there anything I'm forgetting? I've heard competing opinions on thermal glue. Is it worth it? If so, what should I get? Also, my last thing is that I have an MSI 6600GT lying around that I could use temporarily as a graphics card. Would it be beneficial to use that for a while and hold off until prices go down, or should I just take the plunge?
Thank you all for your help, and I'm sorry I asked a lot of questions.
