i have read up on all the cards i want, the problem is if i see 3 of the same type (ie a 9600pro made by sapphire, radeon, visiontek) all with variable prices, how can i choose the one with the best rating if i know the GENERAL specs from online but not the ones of the cards before me (ive read posts and posts about people who've all bought the same card but each one gets diff specs all for the same card)
