For some games, yeah. But, 4-8x MSAA is absolutely ridiculous. Stick to FXAA you'll be fine, or just play with the game's settings a bit.
As for power, it varies on how expensive power is in your area, but averages in the US see a difference of maybe $10-20 a year in power costs between the two. And with a good build, you should be overdoing your PSU a bit anyways to give yourself headroom for overclocks, or just for general safeness.
As a follow up to that then--how much would that build cost you to just get parts? Cause by USD, that's actually a good price. Like, a close-to-DIY price. Still not a fan of the 970 for the future, but right now it'll do you well.
Nope, each card needs to do it's own rendering. They work in tandem to increase the power of the cards, but each card still needs to come up with the VRam in order individually render the image. So, you have say 2 970s. You still have 3.5g VRam.
For the power, just checked a bill, $0.28 / kw, not sure by how much this will affect the AMD card, ofcourse won't game 27/7 but maybe a total of 12 - 15 h/ week, as it will the main pc for use.
How much it will cost to build it (here are roughly prices):
Cpu: 6700k around $450 (from gumtree, new and sealed), around $480 from ebay, new and sealed.
4790k: $450 - $500.
GPU: depends on which one, but wheather it is 970, 390 or 390x, not less than $450.
Mobo: that specific mobo, just checked its price , around $200 but I guess any gaming mobo for overclocking in the $130 - $150 will do the job.
Monitor: that specific one is about $250 new.
PSU: it is gold rated so it's not less than $150.
SSD: maybe about $120 - 150.
HDD: $40 - 50.
case: could be $100, around that price.
Basic wireless keyboard and mouse: around $80 - $100.
windoes:: don't need to buy as I got a copy from uni.
Remember those are AUS prices, to get the USD prices, divide them by about 1.31 ($ AUD has been about 0.76 - 0.77 of $USD), but in Aus you won't get cheaper than those prices, another idea is to buy from Amazon or newegg, but have to keep in mind 2 things:
1- parts price (after converting to $AUD) must not exceed $1000 (AUD), otherwise AUS customs will charge fees.
2- Most of the time, after converting to $AUD and with the handling fees and shipping, prices will be very close to AUS prices, if not more.
If the GPUs don't add up the VRAM, what is the point of SLI then?
If you think I shouldn't get that build, can you recommend the required good parts?
