You pays your money you get your goods ?
Only get as Good as you pay For ?
Precisely, but there is a law of diminishing returns.
As soon as I can afford a three screen racing rig I will upgrade, but then I will not be constrained by case size and can have any card I want to run it.
But believe me, the "running like a dog" type statements are utter nonsense. You might have 600 quid to spend on a graphics card, but it doesn't give you much more other than frame rate. Like me, you're used to running at 30fps on console. The R9 380 (or a GTX 960 if you prefer NVIDIA) gives the consoles a good old fashioned kicking. At 30fps it annihilates them completely.
Not being the latest and greatest, doesn't make them bad cards. Advising people that AMD are bad cards is dishonest fanboi. You're fine because you're all 4k 'ed up, but anybody intending to use it on a 1080p TV (I suspect the majority of those connecting to a TV) would be wasting their money on frame rates that wIll actually damage the experience, rather than enhance it.
Where Kila's card will really whoop the 380 is on a 1440p monitor.
