SO --- then my question evolves:
From what I've read the 285 doesn't really have the horsepower to run 4960x1600 resolution on newer games -- since it is about the equivalent of a GTX670 - which is what I currently have.
There is a good sale on the AMD R9 285 right now at newegg where I could get a Gigabyte card and a copy of DIRT rally for $160 after rebate. That's a decent price to be able to explore the PLP tech for gaming, but I'd buy knowing it isn't really a performance upgrade from what I currently have in the Nvidia GTX 670.
http://www.newegg.com/Product/Product.aspx?Item=N82E16814125679I'd like to consider the 3xx series, but I specifically want driver based PLP support. (no hacks)
Two questions -- will the 3xx series be built on tonga (R9 285) or hawaii tech (used for R9 290x)? (This is all confusing as I've been a staunch Nvidia guy for the last 15 years). I've long had it in the back of my mind that I wanted to try a 3 monitor PLP setup, and if AMD began supporting it - I'd jump to the red team, because Nvidia seems unwilling to do it.
How much money am I looking to spend (wild guesses acceptable) on a 3xx series card that is fast enough to support the 4960x1600 resololution in a way that is meaningful over the R9 285? I am unwilling to spend $500 on a graphics card - no matter how much better. I'd spend $300, however, if it was significantly faster than the R9 285. By significantly I mean 50% faster? maybe?
Thoughts? Should I just sell my 670, buy the R9 285 to try out PLP and buy the appropriate 3xx or even wait a gen and try AMD 4xx when the prices are known, or would recommend waiting till the 3xx series is released because it MIGHT be possible I could get a significantly faster card (say 50% faster than the $160 R9 285) for $300ish or less?
