MSI 670 PE SLI X 2 or 690 for gaming and 3 monitors up to 6 later

[bjkill]

Hi Guys would like to get opinion on the following

Reason for question This is for my Gaming Rig and would like to know if I should stick with MSI 670 PE (Been reading a bunch of negative reviews, even with the 3 year warranty, if I run into issues and have to send back to MSI to fix that would not be preferred).

USE This is for my gaming/work Rig.
Gaming: Like to play mostly SCII, Battle Field, farcry, crisis.
Work: Am in finance and need to have multiple screens when I run models and trading stocks etc. Don't think the modeling is an issue, but need to have at least 3 monitors when working.


Question

1. If I am planning on using multiple displays, right now three (Asus 23 inch IPS x 2 Acer 27 in 3D) and maybe adding another two in the future. Will a single 670 msi PE do the job? If I upgrade, should I get another 670 MSI PE or should I change to a 690?

2. If 690, what brand should I get? Thanks.

For this personally i would take 7990/7970 because of the more vram. However out of the 2 670 sli is nearly as fast as the 690 and quite a bit cheaper so go for 670 sli it will perform about 10% less but much cheaper
