I recently bought an Asus Essentio CM5675-07 which has an Intel i5-650 3.20g processor and 8gigs of RAM. I bought it for gaming but found out, after it arrived, it has a built in video card. I know this sucks for gaming so I ordered a new power supply and a 1gig video card. I know my PC will have to run this "backwards compataible." I keep seeing stuff about "bottlenecking." Is my computer gonna do that? Is it gonna run good with the new card eventhough it's not up to date for PCI 2.0?
