Yup it is tempting isn't it!! I can't believe that I'm actually thinking about crossfire stuff, now that this equipment is so cheap! (That will all change with R700 and D9E however
).
Got the 3870 Powercolor PCS edition coming (800Mhz core & 2400 GDDR4) with zalman style cooler, but no memory sinks
on the way at Christmas, so will be looking to do some serious O/C'ing and seeing how far I can push this thing. I'll be looking for AT LEAST 900Mhz on the core, and hopefully 2600(1300Mhz) on the memory, and then see where we can go from there
Might even give some of the volt mods a go if I'm feeling brave enough and go for 1Ghz on air and see what happens
