Imho, it really is not going to make any significant difference to the average gamer or probably even enthusiast gamer. That said, if you really are looking for one of the best set of RAM modules for an Ivy bridge build right now, the Sammies are the way to go.
You can't exactly compare apples to apples when it comes to RAM because no one does that lol, but look at the following reviews for the Corsair and Samsung RAM, both from Legit Reviews:Corsair RAM
vs Samsung RAM
After that, Google "Samsung MV-3V4G3D/US review" and read forum sites like Hardforum. Read what real users say about it. Actually, reading forums about PC parts is always the way to go imho.
Re the SSD, OCZ is known to have some issues in the past, but I believe that is all taken care of now? Generally speaking though Samsung, Intel, Plextor are top tier SSD brands. Arguably, that group could include the OCZ Vertex 4 & Agility 4, Crucial M4, and others. That is a sweet price, so I cannot argue against it.
