Does this Build sound good for Older games?

CPU: Intel Core 2 Quad Q9450
GPU: Nvidia GTX 570
RAM: 6GB DDR2
HDD: 300GB

and before you say "Get the i3" "get the fx 6300" etc etc, This is a gift PC for the use of playing pre 2010 Games, Such as Half life 2 or FIFA 08. But may play minecraft or such on it.

It shold work just fine

No man you need to at least SLI two GTX 780's. Lol just kidding it looks good.

That Core 2 Quad Q9450 is actually a bit of a bottleneck for the GTX 570 - a bottleneck is when a CPU is not powerful enough to fully exploit the true capabilities of the GPU… It will run games fine enough but it will not bring out the true potential of the GTX 570… But overall the Q9450 is actually comparable to say an i3-2120 and it should run many modern games on high (Crysis 3, Metro Last Light) or even max settings (Bioshock Infinite, Tomb Raider 2013, Batman Arkham Origins)…

Aww. 300gb hdd, thats cute
but if you want to make your whole pc up to "hello kitty" level of cuteness - i recommend you to take 3gb off your ram (3gb ram sounds the way cuter then 6gb…) and get the cutest gpu if all times - gtx260, because it gets so hot that you can cook eggs on it ~(^_^)~

Don't listen to the other guy it seems nobody knows what a bottleneck means i have a AMD A8-6600K with a HD 7970 and i can play all games without problems it matters what kind of monitor your playing on the higher the res the better i play at 1920x1200 and in battlefield 4 i never lag the intel core 2 quad is more powerful then the A8 6600k so you don't have to worry about bottlenecking
