As @Earnist_ said, there is no such thing as 2080ti and "fair price" being used in the same sentence.
If you must buy one though, go for the EVGA FTW model or for the ASUS Strix, OR the MSI Gaming Trio if you want the "Best" card.
For the lower to mid-range cards I'd mostly stick to EVGA for their customer service and build quality, ASUS for their build quality, and MSI for some pretty decent to upper build quality.
Gigabyte, Zotac, PNY and so on will be the brands that are cheaper priced.
