Im planning on building a new computer after my old one broke down, I have a budget of about USD$2300. However as I do not live in the US, I do not have access to super cheap parts on newegg. I would have to live with the prices of the retailers here.
I plan using the computer for gaming. Playing games such as Starcraft 2, Dota 2, Diablo 3 and more. I would like to be able to play the games on high quality settings if not max if possible.
I dont know too much about computer hardware, however I did alittle research. Here are the parts im considering:
That ram for sandy bridge? Sandy Bridge architecture do not have any measurable gains in real world usage from anything better than DDR3 1333Mhz. You could "downgrade" your memory, you won't feel any difference.
The Asus P8Z68 Deluxe is a GREAT mobo, have one
A 750W+ quality PSU is enough for your system (just check slizone for this kind of info, it's a nvidia official website)
I could get a G-Skill RipJawX 1600MHz CL9 8 GB or a Corsair Vengeance 1600MHz CL9 8 GB. Which one would be better ?
Both are good choices, just go for whatever is cheaper I guess. Keep in mind that the Corsair Vengeance has a large heatsink (it's quite tall), so if you are getting an aftermarket cooler, you should make sure that there is enough space.
The HDD Cache (16, 32 or 64MB) is just the amount of data a hard drive can hold in memory. Data in this memory can be read/written faster than the stuff on the drive itself. It's basically the hard drive's own RAM. The larger this cache, the more files can be stored in it for faster access.
In real world performance, the read/write speed of the drive itself is much more important than this HDD cache.
Considering you have chosen a WD Caviar Black, which is a high performance drive at the top of the Caviar range, you are fine.
One last thing, a DVD Drive if you plan on installing Windows or another OS off a DVD. You can put in the drive from your old computer if it uses SATA. I don't think you forgot this, reminding you just in case =P
