[SOLVED] Optiplex 780 GPU/CPU upgrade

I recently purchased a refurbished Optiplex 780 desktop. It came with a intel core 2 duo E7500 @2,93GHz, a 2GB GT 710 and 8GB RAM. I've been able to do lots of things on this computer relatively well but gaming is definitely lacking. I heard that this model can handle intel core 2 quads and I think a Q9550 would do well and maybe a GTX 750TI. I'm not that good with computers but I found out that I might need a new power supply for the CPU and GPU since my 255W power supply isn't enough. What should I do? I'd like to run overwatch at around 70fps on (preferably) high settings - as of now I'm getting 30fps on the lowest possible settings.

I have this PC. Upgraded to a 250 gb ssd (need a SATA splitter), keep the old hard drive and put all your programs on it, buy a Q9650 off ebay.

I'm still trying to find a riser card to stick in a full size graphics card. All the riser cards I can find for the 780 are PCI only. The new graphics card will have to be very low wattage so the power supply can handle it. Definitely try to stay pretty far under the 75 watts the PCIe connection can handle and don't try to use an extra PCIe power connector unless you are looking for trouble. I'm using a low profile Radeon HD 5450 now and I would like to upgrade to something more powerful. One thing to consider on this motherboard is that it is PCIe 1.0. You are not going to squeeze a bunch of data over that slot to make a nice gaming rig. Newegg currently has an Nvidia GT 1030 for $59 after rebate but I think that it is limited to 64bit or some other BS that might make me keep looking.

The desktop, I don't like the SFF or USFF because it's too small and I realised I wouldn't have enough space for bigger components + the PSU is smaller
