I've been working on a build and most people are saying that you should have at least 2GB of vram for triple monitors and possibly more if you want better graphics. Is 4GB overkill since these monitors aren't full 1080p?
Also, my friend tells me 650W is enough but some forums say that you want more than you need. What do you guys think?
My build as of now:
Asus GTX 670 4GB DirectCU II
Intel i5 3570K
Asus P8Z77-V LK LGA 1155
Corsair Vengeance 8GB (2x4GB) 1600 Mhz
Seagate 1TB 7200 rpm SATA 6Gb/s
Corsair Enthusiast Series TX650 V2 650W
Cooler Master Hyper 212 Plus CPU cooler
BitFenix Shinobi Window Black Steel ATX Mid tower
(I already have a DVD drive)
Current price total: $1,178.42
I really want to stay below $1000 but the high end GPU really drives up the price and I don't want to skimp out on the other components because I want this build to last a few years. I can go up to $1200.
A 670 will be great for that resolution. I use a 7870 for 2560x1440, which is basically the same number of pixels, and am happy with the performance. That PSU is great. The whole build looks good to me. It's an odd monitor situation, but whatever floats your boat. To answer your question 2GB is fine, unless you want to use a ton of AA.
So your combined resolution would be 3840x1024 = 3932160 pixels.
A 2560x1440 monitor has 3686400 pixels so you are very close to the GPU needs of a person using that type of monitor.
A 2gb 670 runs that resolution great. I doubt you'd hit a vram bottleneck since your resolution isn't near as demanding as most triple-monitor setups.
The 650w is more than enough for a single 670. A quality 500w or 550w would be enough. But if you plan to SLI later on then you should at least get a QUALITY 750w (making sure it has enough PCIe power connectors for two of your cards).
Otherwise your build looks great and should be a lot of fun!
