If you are looking for 8GB I would go with the CORSAIR Vengeance 2133 or 2400 like THIS
, but I would try to get them on a sale.
Like Tradesman1, I usually use 32GB, but my reason is that I run a lot of VMs. The price of ram is still pretty high, so unless you need it, I would go with 8GB or 16GB unless you see a real good sale on 32GB. I'm still trying to wear out my first SSD (an early X25-M that has around 250TB of writes and shows 100% life), it now lives as an Adobe Premiere scratch disk, so I don't worry much about SSD writes.
