If the single HD6670 cannot play Knight (is this KOTOR? That is, Knight Of The Old Republic), you have two choices, either get another HD6670, or, sell off the HD6670 you have and get a more powerful single card....like a HD6870, HD7770 or HD7850 2GB. The HD7850 alone is probably faster than 2x HD6670 in CF mode. You have a powerful PSU, so your choice of cards isn't limited.

Wow that awesome bro .. noted with thanks for you advise ... but for HD 6870 7770 and 7850 is so expensive
