I'm looking to build a new desktop PC. The only thing I have decided on is the case so far: Corsair Vengeance Series C70.

At first I'll only be using a single GPU but at some point I imagine I'll buy a second one. I was wondering what components do I need to make sure are crossfire capable? And does anyone have any recommendations for doing this for a budget build? In reality I'll probably end up paying more like $700 to $800 dollars. But I'd like to get any recommendations for a build below that if possible. I'm sure I'll add on a few things extra, like a fan controller and some other accessories.
 
Solution
1) The case is the LAST thing, especially if you have an overpriced monstrosity like that
2) NEVER buy for SLI/crossfire with only one card, by the time you can afford the second card something twice as good (but incompatible with your current card)
3) Scrap your case and consider :

PCPartPicker part list / Price breakdown by merchant

CPU: Intel Core i3-6100 3.7GHz Dual-Core Processor ($110.99 @ SuperBiiz)
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler ($24.88 @ OutletPC)
Motherboard: Gigabyte GA-H170-D3H ATX LGA1151 Motherboard ($93.99 @ SuperBiiz)
Memory: G.Skill Ripjaws V Series 16GB (2 x 8GB) DDR4-2400 Memory ($62.99 @ Newegg)...

You simply can't afford anything as good as that if you keep that ridiculous case

On the general things i suppor what basroil said but with some puntualizations.

Case: It's true that the case is the last thing you choose if you are on a low-mid budget pc, but at the same time a good case is something that you only purchase one time and will reuse it in future builds, sometimes if you plan to change pieces in for example 2-3 years periods is not a bad idea to purchase a good case from the start.

SLI: Only plan to mount a Crossfire SLI with a very high end builds that need that power for example for a 4K screen at very high fps, or virtual reality setups. Otherwise normally the drawbacks dont cover the beneficts (more power, more heat, games that dont work with SLI....)

From the proposal i will switch some things the CPU seems a bit weak for me, i trend to favour an i5 with 4 physical cores and the PSU seems a bit overkill in wattage, i would sacrifice the PSU to 550w-650w and the video card (for example using an RX 480 4Gb if you get one at a good price) to upgrade the CPU to a 6400 (60$ increase)
Also think about an proper M.2 SSD, 2+ Gbps are too nice to let it pass, but even the cheapest would be 100$ more


 


Not possible at his budget:
1) The RM750x is an excellent unit and actually CHEAPER!!! than the EVGA G2 550W and Seasonic G 550 I would normally recommend. Tomorrow it might be more expensive, in which case I would suggest those two (which also hover around $80)
2) The 6400 is actually slower for most games, the minimum you would have to upgrade to is the 6500, but either one would put him over his budget by $50 minimum
3) RX480 has a list price of $200 but a street price of $250, makes no sense when the better 1060 6GB has the same street price of $250
4) You can find some 256GB M.2 drives for ~65 bucks, but again, over budget for minimal performance increase in games (though great performance elsewhere)

If OP stretches his budget to $950, all those are great suggestions (except PSU one, again, that one is very cheap right now)
