Is this version of the GTX 970 okay?


It is a really good card but at the same time, there have been issues with coil whine. Thats why i didnt mention it. Asus cards dont have much complaints about this.
EDIT i do believe MSI has a little performance boost (little tho)
 
If you can get asus strix with same or cheaper price than msi reference, go for asus. If cust cooler version, both are good. But in term of performance, msi gaming are slightly better with better oc potential.
