Can I use SAPPHIRE HD 7770 GHz Edition 1GB GDDR5 with my old MotherBoard

I am thinking of upgrade but it seems that won't be able to buy everything at once and now I have very good offer for SAPPHIRE HD 7770 GHz Edition 1GB GDDR5 and a big decision factor to buy it now or not is will I be able to use it with my current system. Now I have this MoBo - GIGABYTE GA-P31-ES3G with :

1 x PCI Express x16 slot
3 x PCI Express x1 slots
3 x PCI slots

Can the GPU use some of this sockets and could there be any problem if I use it like that. And second a little bit off topic but again about the forward-backward compatability - I plan to to change my MoBo with this one : GIGABYTE GA-B75M-D3V can I use my old RAM on this MoBo? Right now I can't write the RAM spec. but from the description of my current Mobo I get this:

2 x 1.8V DDR2 DIMM sockets supporting up to 4 GB of system memory
Dual channel memory architecture
Support for DDR2 1066/800/667 MHz memory modules

Thanks.

  1. i don't see why not. i have a 7770 in my old asus P5n-E SLI mobo that i got in 2007 and have no issues. and all PCI express is backward compatible

    Any PCI-e card will work with your old mobo since it has a pci-e x16 slot, so no worries there. However, you won't be able to use your old RAM modules because they are ddr2 from your old mobo and ddr isn't backward-compatible. DDR2 is obsolete by now so if you want to upgrade your motherboard to the current generation you pretty much have to buy new DDR3 ram sticks.

    Just wanted to be sure, not into builds too much.
