I just put together my first build and I'm somewhat of a newbie. I bought all my parts through Newegg, including my Diamond Radeon HD 4870 with 512MB RAM. Well, I want to get another one and run in CrossFire, but I noticed the the one with 1GB RAM is actually cheaper than the one that I bought. If I go with the 1GB version, can I run these in CrossFire even though they are not *exactly* the same?
1GB version - $269.99 (4870PE51G)
512MB version - $290.99 (4870PE5512)
1GB version - $269.99 (4870PE51G)
