New Build Looking For Advice!!

What is your purpose for this PC? Gaming, Video Editing, Surfing? What type of/specific games would you be playing These would be helpful to know in helping you build.

Primary Purpose is Gaming, looking to play Battlefield and Skyrim on the best settings possible let me know what you think, thank you.

You won't need 16GB of RAM for gaming. Games today barely use 8GB.

Headroom i guess? The build im going for is 16gb RAM, i just dont know whether to get 2x4gb stick or 2x8gb so then i go to 32gb if i want  

Anyway, from the OPs build, i'd reccomend the Asus Maximus V Gene over the Sabertooth as Custom PC (UK) rated the sabertooth at 83% where the V gene was 90% and the sabertooth is £30-ish more expensive and the cooling fans that come with the Sabertooth mobo are "whiny" (these are optional) plus the Sabertooth doesnt have a POST readout or any onboard power buttons.

I've just seen that there is only 1 storage device listed there. Its not that much more to get a 1tb HDD if you wanted you know, it can be there just to store crap off of the SSD too.

As for graphics, i looked on google but i kept finding the 7850, not the 7580? For example, this link --> http://placi-video.flax.ro/placa-video-msi-ati-radeon-h... is listed as a 7580, but the box shows 7850?  

Personally, i've moved away from ATI cards and gone back to Nvidia, i kept having loads of different issues with my ATI HD5870 1gb.

@ Trundley

Thank You for your feedback and advice!! Will definitely look into the MOBO! I have to apologize i am new to posting here and am learning quick on the basic guidelines. I should have put in there that i have extra HDD's in excess of 3.5TB that i am also going to put in there. The graphics card was a typo lol, it is the 7850! Sorry bout that. And yes i like the idea of future expansion and also $$$ is not an issue for me. I was just trying to be reasonable and go with quality parts. Again TYVM Trundley!

In my own build i've went for the Nvidia GTX 670 which is a new release i am told, and if money isnt the issue, i'd prompt you to go for that. You could pay another £100 and ge tthe GTX 680 but its only fractionally better than the GTX 670.

Check this link for the GTX 670 vs the ATI 7850HD

"CPU = Intel i5 3570 Ivy Bridge"
--I imagine you meant the i5 3570K so that you can OC.

"MOBO = ASUS Sabertooth Z77 LGA 1155 Intel HDMI SATA 6GB/s USB 3.0 ATX"
-- I think the above suggested ASUS or the ASRock Z77 Extreme6 would be great
ASUS Maximus V Gene $190
http://www.newegg.com/Product/Product.aspx?
ASRock Z77 Extreme6 $175

"RAM = Corsair Vengeance 16GB (4x4) 240-Pin DDR3 SDRAM 1600 Dual Channel"
-- that should be fine, 8GB wouldn't really be much different, but if you want to go 2x8 you can save room for later or you could look to improve your CL which is not vital but if you are willing to spend extra $ to get the best of the best a CL 7 would be really nice
Corsair Vengeance 16GB (2x8) 1600 $120
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Corsair Vengeance 16GB (4x4) 1600 CL 7 $165
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

"Graphics = Sapphire Radeon HD 7580 OC 2GB 256bit GDDR5 PCI-E 3.0"
--if you could sport that cash for GTX 670 then go for it. If you are trying to keep it more in the $2-300 range then I would suggest:
EVGA SuperClocked GTX 570
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

"Hardrive = Crucial M4 2.5" 64BG SATA III MLC Internal SSD"
--Great.

"PSU = Corsair Enthusiast Series TX650 V2 650W ATX 12V High Performance"
-- if you are going to want to OC your system and set it up for the future of maybe SLI/Crossfire you might want to go with a 750w
OCZ ZT 750W fully Modular (which I like) $90
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
Or Corsair Enthusiast TX750 (not modular) $90
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

"Case = Antec 900"
--great case for $, if you want to save $ but not have 3.0 front ports but similar
Antec 300 $70
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

If you intend to OC you will need a heatsink fan at the least or a water cooler if you plan on high OC and lots of gaming.
CoolMaster Hyper N550 $29
