thatsmynamedude, good lord. That was amazing. So link me some stuff
i manually upgraded my case because my computer is on nearly 24/7 so i had to get something with a little more airflow.
Sure, no problem. Glad I could help.
Firstly, for the ram, reuse it or get the cheapest ddr3 1600 8gb kit you could find.
As I said, power supply you should get a 80 plus psu 750watt for future expansion. You will hate yourself for not getting enough power if you want to do sli in the future.
For the motherboards, I would recommend the asus lineup of P8 series motherboards. Ledgendary reliability excellent drivers. Never heard of any issue with them. Go with either the Z68, Z75, or Z77 chipset. If you do not want to overclock or want to save some cash on motherboards, you could always go for the non-overclockable H77 which was what I chose.
A z68 V LE motherboard from asus will have no problem hitting 4.4ghz on the overclock. But your CPU is not a K series one. Either way, I would recommend the Z68 V LE, Z77 V LK or higher, depending on your budget.
For graphics card, I would go for a high end single card solution. Either a 7950 or a gtx 670 or higher. For your games, a 7950 would be very very cheap and will perform like a champ. Therefore, I would recommend a non reference cooler on that and overclock it.
To sum it up, you will need a new gpu, psu and motherboard. Maybe not so much on the motherboard as it can hold a i7 2600. I think it would be a H series motherboard though. Anyways, maybe you dont need a new motherboard. Check if the motherboard has a pcie 16x slot which it should.
Ok, get a new gpu and a new psu. that would be my recommendation. As usual, for psu, I would get corsair. But I found out this psu company called FSP group. They have great PSUs. maybe you might want to check them out.
For the GPU, if you insist on a gtx 680, just get the 2gb one. I highly unrecommend getting cards like FTW from evga. Only cards I recommend from EVGA is their hydro copper and stock cards. The rest is just a cheap gimmick and a waste of money. Rather go for msi or asus. For your case, a gtx 670 or a 7950 would be excellent.
Good luck on your choice
