i also bought my comp 5-6 months ago now. and if u could get a GT for half a GTX and have nearlly same perf is another really needed for 40% extra perf for 200% of price? if u want to spend more money then go ahead but i say save it. coz sli is outdated easily. yeah the GT is really good for price but really soon new cards will overtake it and ur stuk with 2 cards that are less then what 1 9 series can do
