You are able to use Forbidden Lance on Clear Vice Dragon and it'll indeed lose 800 Attack after his Attack is double the Attack of the opponements monster. Example: You use Forbidden Lance on Clear Vice Dragon and then attack a Elemental Hero Burstinatrix(1200 Attack Points) with it, then your Clear Vice Dragon's Attack Points get 2400 and he loses 800 Attack Points because of Forbidden Lance. So he'll end up with 1600 Attack Points.
Any of the dual-headed Radeon 2400-2600 cards should work fine. Size the OS with what you want the machine to do, a sever is what it is, not a gaming machine.

Under normal conditions, Chainsaw Insect, I believe, @ 2400. However, in a Skill Drain deck (which you may want to consider with Chainsaw Insect anyway), Beast King Barbaros is strongest @ 3000.
