Now that the genie is out of the bottle with the R9-290X @ $550US which is slightly FASTER than a Titan at virtually HALF the price (!!WOW!!),... ...pause for a moment to contemplate that!... ...I'm soooo ready to get Metro Last Light when it comes out for Linux!
Nvidia will be dropping prices within 2wks I'd say unless they're complete imbeciles!
In the end, us gamers get to choose which one to pick and play at a much more affordable price with the the latest AAA titles merely a few weeks to a couple of months away for Metro LL; and perhaps a few to several months away for the rest of the AAA's which will come inevitably with SteamOS!
In the end of it all... It will be an awesome gaming year for Linux next year and it is JUST THE BEGINNING!
