I am new at upgrading systems and my current computer was put together by a friend that is now outdated.
My current set up. (please forgive if I am missing info, I am not tech lit)
GA-MA785GT-UD3H mother board
Amd 440 rana chip i think its a 3 core, I couldn't get the fourth core open
16gb ram 4X4
crossfire 2X5700's 512mb each.
650w PSU
1 tb hard drive
now running windows 7
I am currently living in China and during my visit back home (Canada)I bought a Sapphire r9 280x toxic card without checking to see if it would fit my comp at home in China. Impulse buy ....that and Titan fall.

I would like to play games like BF4, Skyrim, GW2 ,titan-fall and newer games coming out on a res of 1080, I got this card so I can play at the highest possible settings.

I have been reading over the forums and searching online, and realized that
1. My board supports PCI 2x and the card is PCI 3x ... according to what I have read this may not be a big issue with only a slight loss to GPU performance. (would love a confirmation)

2. My CPu is kinda old and an upgrade is needed, blew my cash on the GPU
I can upgrade max to a 1090t on my board to avoid buying a new mobo and chip(wanted I5 4670k and asrock z87 extreme4,6 which oddly enough is more expensive here in China then back home.) but I can find a 1090t for about 133-145 USD.

My question is would the old Rana AMD 440 be enough to keep up with the toxic card if I can install it on this board..I assume it wont....
and will a 1090t be enough as an upgrade as i think that's the best chip I can go with on this mobo.

Lastly
3. Since my board is older?? can it power the r9 toxic?? My previous two other cards at crossfire where just plug into the slot ... but the r9 has a power source plug in , two actually ..

Do i plug it into the board or to the PSU directly ??

its been a tortures 2 weeks reading forums and waiting, I have not put in the new toxic card in yet in fear ill blow something up.

any advise would be helpful, also taking it to a tech here in China I am rather dubious about since I don't know squat about hardware... worry they'll swap parts etc.. that and I really cant speak Chinese.

Thx in advance

1) Yes, your motherboard will accept the new graphics card; no problems. There may be a slight (not noticeable) drop in performance.
2) Depending on which revision of the motherboard you have, it may require a BIOS upgrade in order to support the 1090T. Motherboard revision numbers are normally printed on the corner of the board itself ("rev 1.3" for example). I would definitely recommend a CPU upgrade to help support your new graphics card.
3) Your motherboard is capable of supplying up to 75watts of power through the PCI-Ex16 slot. Since your new card requires more than that, it has the additional power ports. These need to be connected directly from your power supply. If your power supply does not have these power cables (normally labelled "PCI-E"), then either a new power supply is required or just some power adapters (molex to PCI-E).

Thanks for the quick response Wolf,

I went ahead and installed my new Gpu to my board after reviewing your comments, my psu did have 2x 6+2 pin power cables.
Man the card is huge ... I had to cut a bracket inside my case to make room for the Toxic, but once installed and powered everything went well ... no explosions lol ..I guess I was worried for nothing.

I have not upgraded the CPU yet but I will, thus far I am able to run most of the games near max everything, I am not able to see or can tell much if the CPU is bottle necking, but it must be.
GW2 all max settings I was reaching 34-50 fps, I was able to play titan fall on insane settings .. man games look so much better.....Skyrim maxed .. oh so nice.... next BF4 after the chip upgrade....

Thx again for the suggestions, it made it less stressful to go on ahead and pop in the card.
Next is the chip upgrade.
I will take a look at the reference and make sure the bios is upgraded if needed.
