I never said anything that equated to "SLI = expensive". I said that given that you were this type of person:-
Code:
if (p4_3ghz_at_4ghz && fridge_cooling && muchos_wonga)
printf("D00d, my dad's your dad's boss! LOLOLOLORZ!!1!");
You would buy expensive.
As you later said, the cheapest option for "SLI" are actually a couple of 3dfx Voodoo2s. I have a magazine somewhere showing a guy running Doom3 on them. :cool:
Fridge cooling might be a decent option (Particularly if you have space in your case for a six-pack), but the problem with heat pumps like that is that while it's very cool inside, it's a fair bit warmer outside, although I suppose if it's only coming out on your feet that's fine.
