I was thinking about upgrading my graphics for better gaming.

What if I put a 2.0 version using graphic card?
Would it run??

Thanks for the reply. Yes, you can replace the PSU with a different wattage without any issues. However, when you select the PSU, make sure that it has sufficient connectors to support the HDD, ODD and has the connector which suits the graphics card (if the graphics card requires additional power supply). 

Some 2.0 PCI graphics cards are backward compatible with 1.0. However, if you install a 2.0 graphics card on a motherboard that supports 1.0, the performance of the 2.0 graphics card will be reduced to 1.0.

This means that the 2.0 graphics cards potential will be reduced to 1.0. 

Hope this helped.

@justin12,

To clarify your inquiry, and so all can understand, here is your initial post.    As your computer is a p6703in model, with WIn 7, 64 bit, and is a "legacy" BIOS, it is not capable of using the newer UEFI BIOS graphic cards.  Your question on the GT 710 is then moot, as it will not work in your computer, as it's a UEFI card.

Please mention a sampling of the games you wish to play. Or go here and answer the "Can I Run It".  I do belive the i3-550 will be a bottle-neck (problem).

@Chimney_83,

That model as an i3-550 processor, and is PCIE x 16 version 2.

Thank you so much sir.

Because your i3-550 is a first generation (2010) chipset,   I can not input the i3-550 1st Generation into the search parameters.  Plugging a GPU card into an older model 2010 chip set is foolish without the test.  Please login to the Can I Do It module. Let it test your chips.
