Excellent card. Does not faulter even when running 4 games at once and still leaves plenty of graphic processing power for other applications. I am using just one of these PCI-E cards and am suitably happy with its results so far. I am running three accounts of one particular game and one account of a different game. Both games are very graphically power hungry but I experience no latency / lag problems when playing and often the games are running in the background whilst I use other applications that are maybe not so power hungry, again with no problems. The Installation was easy enough however you should realise that this card is a bit of a monster size wise as it takes up considerable depth space, so it would be wise to choose a motherboard and case that allows such space, (it does however look a bit tasty through the perspex side of the case). I have owned several PCI-E SLI cards over the past few years and think that this card out performs the others. It would be interesting to hear reviews from anyone using two of these cards in SLI. Highly reccomended.
