Building My Own Gaming Computer

Well, my Dell Optiplex 620 is a piece of junk and I'm looking to play some real PC games (Like Call of Duty: Black Ops). I've never built a computer before but I've been researching a lot lately. However I still need a ton of help, so I'm turning to you guys. Here's what I've compiled so far: 1.Processor Intel Core i7-860 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor BX80605I7860 2.Motherboard GIGABYTE GA-P55A-UD3 LGA 1156 Intel P55 SATA 6Gb/s USB 3.0 ATX Intel Motherboard 3.Memory (RAM) G.SKILL Ripjaws Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9D-4GBRL (newegg) (maybe I could get 2) 4.Hard Drive Western Digital Caviar Blue WD6400AAKS 640GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive 5.Graphics Card HIS H587FN1GD Radeon HD 5870 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card 6.Power Supply CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply 7.DVD Rom 8.Sound Card (optional) Creative 70SB073A00000 7.1 Channels 24-bit 96KHz PCI Interface Sound Blaster X-Fi XtremeGamer 9.Computer Case AZZA Solano 1000 Black/Black Japanese SECC Steel/Metal mesh in front ATX Full Tower Computer Case 10. Operating System – Windows 7 64-bit Do I have all the parts I need in order to build the computer completely? Are all these parts compatible? Are there any other parts you guys recommend that I should get? Or can I get some cheaper items that are just as good as I put here? Sorry for all the questions, but I really do need some help. Thanks!!!!!!!!!!!!!!!!!

yes all the parts are compatible. yes that's all you'll need. just one suggestion tho, i think i'd save some money and use the motherboards onboard sound and forget about getting the sound card, if you find it's not good enough(which i doubt) for you, then you can always add the sound card later.

Suggestion noted. Thanks terry!

That looks like a success! Good Luck!

Okay I've researched and I think I've picked out the right components. However, I'm not 100% sure if they are 100% compatible. Can someone please help me out? I've done plenty of research, but I'm just not completely sure. Here are the parts: (remember to look for some newegg coupons online) 1.Processor Intel Core i7-860 Lynnfield 2.8GHz 8MB L3 Cache LGA 1156 95W Quad-Core Processor BX80605I7860 2.

This is definitely pricey, so I have to make sure it's going to work before spending so much money. Thanks guys!!!!!!!!!!!!!!!!!

again yes all will work together, even tho i preferred some of your choices in the first post, like psu and motherboard, adding the ssd though will be really noticed and is a good addition for a gaming pc.

dont go for 8gb ram 4gb memory will be enough for now, you can always get more later

usually better to get ram in matched sticks so if your intending to have 8gb and can afford it now then always buy an 8gb set instead of 4gb now and 4gb later.

I agree. and i beleive that would go for any hardware on your system, dont mix hardware. for example different drives, ram, cards…and I dont know about others on this site, but my personal opinion would be to get and AMD motherboard. I have had quite a bit of success on those.
