hello
i have a gtx 650ti boost which is pcie 3.0
and a motherboard which has
PCIe x1 Slots, Generation 1, 2.0
PCIe x16 Slots, Generation 1, 3.0
but my cpu dose not support pcie 3.0(i3 3220)
so should i connect the card into pcie 3.0 assuming it will run at pcie 2.0 or
to the pciex1 slot and why dosent the board have a pcie x16 2.0
is pcie x16 2.0 = pcie x8 3.0

Uhmmm the CPU doesn't determine support for PCIe, last I remember, and 3xxx chipset did support 3.0 last I remember. That said, if you put the GPU in the 2.0 slot, then you will run HALF the bandwidth as compared to 3.0 slot, thus 'half' the performance potential of the card. Simply put it into the 3.0 slot, and disable your IGP, move the cable for video, install NVidia latest drivers, done.

desagree, i3 3220 DOES NOT support PCIe 3.0 :
http://ark.intel.com/products/65693/

Ivy Bridge only from i5 and up supports it, for instance:
http://ark.intel.com/products/68316/Intel-Core-i5-3470-Processor-6M-Cache-up-to-3_60-GHz

So it does not matter wich mobo you use, you will be limited to PCI Express Revision 2.0 speed when using PCIe3.0 cards on i3 3220 CPU.

ACK! I HATE THAT... they make the 3xxx series of iCores in 2012 and 2013 and everyone is selling PCIe 3 cards now, but then make the only the i3 cores run still older PCIe 2.0 while the rest run PCIe 3.0 ! Grrrr... Sorry for my mistake, but that pisses me off. It is hard enough to keep up with the many MODELs of the same CPU in a given year, but then they have to pull that sort of crap too of using legacy standards instead of modern standards like the other CPUs they have. Sighs.

However Haswell i3 does support it (PCIe 3.0), wich is a great news for most budget mortals.
