upgrade or not ?

[AgedIdiot]

Am suffering with upgrade'itus
Have calculated that if I sell my 2 x 290's with their blocks I can afford to get a 1080 + block.
But performance wise I have had no issues so am at a losd to put forwatd a reason for changing. Thoughts?

Single card will mean less crossfire related issues. If the cost is negligible I would go for it

Always go single card if you can.

and if your old kit covers the price of the new kit (or that you are comfortable with) its a no brainer.
