Thanks! The EK set up is very nice looking, but I do worry about the nickel cpu block. The RX kit looks dull
Yeah I realized an extra 120 radiator and 2 GPU blocks are adding up to over $500. I know you got to pay for 'fun', but still got a budget right now, plus I won't be upgrading to CF until I need to. So by then I will worry about GPU cooling.
The only reason IMO to go crossfire if you've got a 6870 is for crossfire, otherwise I'd just get a faster single-card GPU, and the resale value of 6870s are decent enough, especially considering you can pick up a 6950 2gb for $230ish after rebates.
Stick with CPU cooling for now, and save up your pennies for later. I had to pull the trigger with the noise a single 6950 made under eyefinity loads, but I had to do it bit by bit, first with a GPU kit, then expanded to a waterblock, then a second 6950, then a second waterblock. Yay for graduation money!
