So as the title says I need to build a new PC. The last PC I built was back in 2000 and back then it was actually cheaper to build the PC from scratch. Technology has changed so much since then I just simply don't know what to look for when building a new PC. Is it even worth building a PC from scratch or simply purchasing a pre-built PC from like Dell?
You can do a lot better than that for $1929 if you buy from newegg and build yourself. I'm going to assume you're not into overclocking and don't have a strong preference for any particular company (Intel/AMD, nVidia/ATI, Asus/Gigabyte, etc).
Total about $1850 if I added them up correctly. You save about $100 and get a much better gaming machine.
Edit: When I started typing that there was only one reply in the thread OK, if you prefer nVidia, change the HD 4870x2 to a GTX 280 or a 9800GX2. Plenty of benchmarks on the Web so you can compare what each card can do.
Now when looking at gaming, how much of a difference is a Quad going to be over a Dual?
My ultimate goal is to build a good PC that will last. I'm afraid that if I stick to a dual that the Quad I should I purchased now runs apps and games much better down the road.
Read this article. My own conclusion from it was that a quad does have advantages over a dual in gaming, but they're not major. It depends on your favorite games (e.g. in FSX a quad is much better than a dual), your resolution (at lower resolution the CPU matters more), your video card (they used a HD 4870X2, fastest card these days, so they had no bottllenecks; if you get a weak GPU it may be a bottleneck and then any CPU will give you the same fps). http://www.legionhardware.com/document.php?id=770&p=5
Thank you so much for that post aevm, it is very much appreciated. I didn't notice a power supply listed. I'm assuming 700w+ that is SLI ready or compatible?
It's there The Corsair 750TX is a PSU. It has 750W. It's powerful enough for a GTX 280 or a 9800GX2.
Do you think you'll ever want to add a second video card in SLI? If yes, forget the 9800GX2 because that one won't scale well in SLI (it already has 2 GPUs, and SLI with that means 4 GPUs, not well supported). Get a GTX 260 or GTX 280. There's also a "GTX 260 Core 216" - think of it as GTX 270 to keep things simple. http://www.newegg.com/Product/Product.aspx?Item=N82E16814130398
The problem in this case is that you would need to spend more on the PSU and the motherboard. You'd need something like Corsair 1000HX or Galaxy 1000W or similar, and a SLI motherboard (eVGA 780i, XFX 780i for example). That adds about $150 to your PSU cost and another $100 or so to the motherboard cost, so do it only if you're sure you will add that second card.
