Which GPU should I buy?

[Oscar Wiley]

Hey guys, I have a gaming rig that I custom built online, I currently use a 680, but I'm trying to decide between one AMD Radeon HD 7990 or dual GTX 780s. Here's a few rig specs

Intel® Core™ i7-4770K 4.3 GHz 8MB Intel Smart Cache
2TB (2TBx1) SATA-III 6.0Gb/s 64MB Cache 7200RPM HDD
16GB (8GBx2) DDR3/1600MHz Dual Channel Memory
MOTHERBOARD: [CrossFireX/SLI] ASUS Sabertooth Z87 Intel Z87 Chipset DDR3 ATX Mainboard w/ TUF Thermal Armor, ASUS Remote GO!, USB Charger+, 7.1 HD Audio, Intel GbLAN, 3 PCIe x16 (2 Gen3, 1 Gen2) & 3 PCIe x1 (All Venom OC Certified) [+136]
POWERSUPPLY:1,000 Watts - LEPA G1000-MA 80 Plus Gold Certified Modular Power Supply

In your case I'd be inclined to go with the 780's in SLI - all multi-GPU configurations have micro-stuttering issues in games but AMD's seems to be more noticeable (reported to be driver related according to this article http://www.tomshardware.com/reviews/catalyst-13.8-frame-pacing-crossfire,3595.html ) so if you're looking to game and you want the best experience available, IMO you're better off with the NVidia cards in SLI, at least at this point in time

How many monitors? What resolution?
Any of the SLI/CF solutions mentioned are mad overkill for any single monitor.
