Hi, I've never built a PC before but I've done some research and think these parts will work with each other but I'm not 100% positive.
CPU (No air conditioning in summer so I can't overclock unless I want a damaged CPU lol)
Intel Core i5-2500 Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 2000 BX80623I52500http://www.newegg.com/Product/Produc...82E16819115073
Motherboard (Expensive but has PCIe 3.0 and I've read that 3.0 cards won't work on 2.0 boards)
ASRock Z68 Extreme3 Gen3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboardhttp://www.newegg.com/Product/Produc...82E16813157271
RAM (Heat spreaders because of the no air conditioning, house can be 90 degrees in summer)
CORSAIR Vengeance 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model CMZ8GX3M2A1600C9http://www.newegg.com/Product/Produc...scrollFullInfo
HDD (Went with blue: not as loud as black but faster than green)
Western Digital Caviar Blue WD5000AAKX 500GB 7200 RPM 16MB Cache SATA 6.0Gb/s 3.5" Internal Hard Drive -Bare Drivehttp://www.newegg.com/Product/Produc...82E16822136769
Optical Drive (I assume any drive will do?)
ASUS 24X DVD Burner - Bulk 24X DVD+R 8X DVD+RW 12X DVD+R DL 24X DVD-R 6X DVD-RW 16X DVD-ROM 48X CD-R 32X CD-RW 48X CD-ROM Black SATA Model DRW-24B1ST/BLK/B/AS - OEMhttp://www.newegg.com/Product/Produc...82E16827135204
GPU (I believe there was a cheaper 7850 but all the reviews said the fans made a lot of noise)
SAPPHIRE 11200-01-20G Radeon HD 7850 2GB 256-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card OChttp://www.newegg.com/Product/Produc...82E16814102984
Case (Will the front fans be able to work with the front panel closed?)
Corsair Obsidian Series 550D Quiet Mid-Tower Cases CC-9011015-WWhttp://www.amazon.com/Corsair-Obsidi...3550915&sr=1-4
PSU (I know to go 80+ but don't know how much power I need.)
??? (I don't know how many watts the motherboard, case, HDD, RAM will take up?)
Total should be around $1,200.
I was hoping to go more along the lines of $800 or $850 but got worried that a GTX 560 would be underpowered when the next gen of consoles comes out so I went over on the GPU. Also the PCIe 3.0 made me go over on the motherboard thinking all cards in 5 years will be 3.0 only and won't work with a 2.0 motherboard.
Thanks for your help.
