the xfit has a low profile expansion slot for like a hd5570 or hd5450 not a full sized one like the hd 5670, but if you keep the top case open you should be able to fit the card, it wont be pretty but itll work. and the power supply seems sufficient enough.
you could also get a low profile version of the hd5670, the height would be fine but the width would be to wide, it needs a double low profile slot which the xfit does not have. you could modify the case/drill a hole on the side so itll fit
the hd 5670 is either too wide or too tall to fit properly in the x-fit case
but with some modifications you could make it work.
Depends on the size of your case and your motherboard.
The 7990 has not yet been released. In any case, the size will depend on the manufacturer.
It is called in SLI in case of NVIDIA and Crossfire for Radeon.
All ATX-standard computer cases are compatible with all ATX-standard power supply units. Another issue is the selection of a PSU suitable for your computer components - what is the current consumption of your computer?
It depends, measure your cards' length, if its under 35cm it'll fit.
Very likely, what I'd look out for is whether or not that setup works in your case. In my case for instance the PSU blocks my second PCI slot.
Yes it does, i have one inside my antec 902 case, but its a tight fit.

In the case of having an ATI HD 4330 in your laptop, it is vital what the other components are. Most of the time, the game will run just fine, for example: I have a Radeon 3450 and it runs it quite well at 800x600 and 1024x768. (Quite fine in this example means: Average FPS is higher or equal to: 25-30) In case your laptop has 1 or 2 GB of ram, i'd suggest to upgrade the RAM before trying to play the game. And although the HD 4330 is part of the newer builds of ATI, still try to use quite lowish settings, because the chip still isn't up to power like desktop-builds varying from the X1950XT up to the HD4870.
The M means mobility = it takes MEMORY from the entire PC (the ram sticks)... so in this case, there is 256MB >ONLY< dedicated to the graficcard (which isnt alot), and if your game needs more memory, it will take from the RAM... = slower pc = slower gaming so generally avoid M cards for gaming..
$539.99...well that's what it costs. It's worth will be defined if it does what you need it to do and how well it does that.
Both. "Case sensitive" means that upper case and lower case characters are treated as different characters.
