Will Gtx 660/670 fit to my computer?

Solution
1.- every card may have a different length, yes... some can be as large as 14" I think... but they all fit in the same PCIe slot, it is the bulk of the card that can get really long. You need to check for video card max length (this is GPU clearance) that fits in your pc case.

2.- check what model is your power supply, and whether it has the needed PCIE power connectors... they can be like this

Tell us whether it is 6 pin, or 6+2 pin (like in the pic), and whether you actually have only 1 or 2 of these. When purchasing the video card, it tells you how many PCIE connectors needs, it could be 1x6pin, 2x6pin, 1x8pin etc.

so, that's 2 things you need to check before purchase... 1.- whether it...
if this is your MoBo:

It will work fine. It has a pci-e 2.0, the card you want may be pci-e 3.0 but they are backwards compatible and there is no loss of performance (GPUs aren't using the full pci-e 2.0 bandwith).

I would be more concerned about your pc case... google your pc case, search for GPU clearance in the specs, compare it to the card length of the GPUs you want.

Also, check if your power supply has the needed PCIE connectors that these cards need...
 


Okay so every graphic card has it own size?
 


right now i got

CPU #0 Intel(R) Core(TM)2 Quad CPU Q8300 @ 2.50GHz, 2506 MHz
