Best GFX card for sabertooth z77 + i7 3770k?

[Imulate]

Hey

I am starting to save up for a new graphics card, for my system:

i7 3770k
sabertooth z77
g.skill ripjaws 2x4gb 1600
1200 watt PSU
and currently a asus 650ti
I run ubuntu 12.10
I don't overclock.

My current card runs fine for my current needs, minecraft and flightgear. But steam will have some really good linux games in the cumming months and I will want to play at full HD settings. Plus I am getting into developing webGL applications and a powerful workbench will be nice.

I am look at 7800 - 7900 series cards but I want to know what will operate best on my setup? Brand specific?

Also would I be able to run 2 different graphics cards at the same time? ?If so, will it use it efficiently?

I will probably purchase it when the price drops ready for the next generation of graphics cards...

look for asus or saphhire hd 7950 3gb gpu.they are bang for buck.you donot need 2gpus,single is fine.

in nvidia look at gtx 670

I do not know if it still is but at one time Nvidia had the better drivers for Linux. In which case I would go with a GTX 670. I do hope they get more Linux Steam games out I know the last time I booted into Ubuntu out of 224 Steam games there were 6 that would work with Linux and that was just last month. It is some what better on the OS X side as I had 66 that would work on my Hackintosh out of the same 224.

so I'll go for the 670, maybe even a 680. Thanks guys!

Oh, about multiple cards, would I be able to use the 650ti with the new card, just as extra processing power? Or would it just use up PCIe lanes and make the entire thing slower? Sorry I don't know much about modern computers...

You can't SLI it with 680 but you could technically have it in the rig and make it operate as PhysX dedicated card, in which case it might take some stress off of your main graphics card in games that support advanced PhysX. All of your monitor cables would be plugged into the main graphics card and no, you don't need an SLI bridge for the PhysX dedicated card.

See Nvidia site for more details, and how to dedicate a secondary card for PhysX. Video kinda old, but related as well:
