Firstly I would build it myself as you get better parts for less money and a better computer when it's finished.
The Exception here is I wouldn't be considering any NVidia Chip Set Video Card at the moment as they have issues with a possible Design Problem by Nvidia. If this is proved it will render every NVidia Chip Set unusable in a very shot period of time and as you want this for gaming it's far more likely to be pushed hard and overheat the Video Chip Set Chips. As I don't know this Model of system I would want to know who makes the M'Board Chip Set and which one it is. Again if it's a NVidia Chip Set avoid it like the plague as there will be problems which the system maker [b]Can Not[/b] fix. This will render the system useless in very short order and you'll be out of pocket for this unit.
There should be some Custom Builders in your region if you are uncomfortable with building it yourself and they can build it for you and at the same time recommend the best parts to use. Many Times First Time Builders look at the parts which they consider best for them and buy accordingly but the individual parts are incompatible with each other or just the wrong technologies to be used together so a Custom Builder who specializes in this type of system will be able you guide you as to what works best together. And don't forget the Power Supply this is overlooked as Unimportant and provided it's over 450 W it's good enough. This is wrong and there are two types of PS's those that are rated to a Continuous Power Output and those rated to a Peek Value. You want a PS that is rated for Continuous Power Output as these are far Superior and work better protecting the internals of the case from the mains supply.
And $200 for a Video card is very expensive unless it has a very fast GPU and at least .5 GIG of RAM. This Video Card [i]Inno3D GF 9600GT PCI-E 2.0 512MB DDR3 256-bit, Core clock: 650MHz, Memory clock: 1800MHz, Dual Dual-Link DVI, HDTV, Fan, HDCP, 64 Stream Processors, nVidia SLI Technology, 128-bit Floating Point High Dynamic-Range.[/i] has a RRP of $169.00 AU Dollars which should be less in US$ so I would want to make very sure that they are at the very least offering the 512 MEG Video Card and not the 256 MEG Video Card which has the same specs with less RAM and is cheaper Card. You need to remember here to subtract the cost of the Standard Video Card as the Builder doesn't supply 2 Video Cards when you upgrade the Video Card. Of course if the standard Video Card is On Board the system is not a Gamers System never was and never will be so forget it all together.
Similarly if you look at the price of Corsair RAM 2 GIG costs you $379.00 AU but if you look at 4 GIG of the same RAM it costs the grand total of $429.00 AU so for the extra 2 GIG of DDR3 RAM it costs you another $40.00 AU. That is hardly anything like $200.00 US and I can guarantee that you would be getting much cheaper RAM than Corsair in any pre built system.
