That is a serious piece of hardware. Are you sure the PC supply has enough headroom to power it?
This was my gaming rig til about 7 years ago; when the MB poofied it got rebuilt into a generic mid-tower as my daily driver. OCZ 450-12U was a pretty stout power supply for its time; actually a derated 550W PSU. But 240 watts for the card and 135 watts for my antique 1055T are still gonna push it, IF I actually find some software that will run on my old beast that CAN make the card break a sweat.
My problems are a little more primal now; I'm gonna need a really, really long shoehorn for this one.
I'm hoping I can skate a little longer on this build; I wanna make an even decade on that 1055T & 16GB of Crucial Ballistix DDR3. I'll spring for a new case if I have to... but if I have to go new MB, I'm gonna just buy something 8700-8800K or better used and beat it like a rented mule.

I'm looking to run a flight sim on Steam at 1080P, not some 4K twitch-trigger First Person Shooter boolsheet. Linus did almost the same exact thing I'm doing in the video above, just to show that prehistoric hardware can still perform if upgraded with modern graphics cards. The Q9550 he uses is as old and 2 fewer cores than my 1055T; and I know for a fact I can run it at 3.8GHz all day with that Silent Copper cooler.
I think it's gonna be an interesting experiment!
