Roughly $300 US, maybe a bit less.
Personally I mainly want it for PhotoShop work and other 2D graphics editing/creation, all reports I've heard have stated that Matrox's 'GigaColor' has an immediately evident impact.
Icrontic had a nice write-up on the impact of it.
That paired with Matrox's typically stellar 2D image quality make for a very pleasant time.
I'll be interested to see how much GigaColor impacts DVD's, and older games that don't need more then 2bits of alpha.
And finally I can get Matrox 2D, along with solid 3D.
It has the best 3D feature set available, along with an excellent FSAA implementation that looks to provide a minimal performance hit while retaining fantastic visual quality. I've heard some pretty pleasent things about the flexibility of the TV-Out implementation also.
Granted, it doesnt hold up to the R8500/GF4 Ti42000 regularly, but it gets decently when FSAA is applied.... and none of the games I typically play are truly dependent upon the graphics card anyway.
Triple-head has it's benefits... but I'm expecting the only gamers that would really see a huge benfit from it will be those interested in flight sims. I could probably benefit decently from it when multi-taking while doing heavy 2D graphics editing, but I'm not sure that the cost of a third monitor would make equate to the flexibility I'd gain.
I couldnt care less about gaming on even two monitors, so triple-head gaming is useless for me.
I'd strongly prefer if they allowed higher degrees of anisotrophy though, and FAA has a few areas wherein it misses jaggies that could be worked upon.
I just can't justify $400 though, and even $300 is pushing it... but since I'm only barely satisfied with my current Gainward boards 2D, and the the Parhelia seems a match made in heaven for the multitude of 2D graphics editing apps I could probably pull $300 for it.
