Don’t you just love how everytime you purchase some new technology, the next version is just around the corner? It always seems like you have a very short lived time until whatever you have bought new becomes obsolete. Fortunately I like to think otherwise, and my strategy towards building gaming computers is to build a gaming pc that has a certain level of value which will allow it to perform well, even if it is two or three generations of technology old. That being said, every time you purchase a new system, it can be prudent to ask – what is next? Should I buy new now or should I wait? Should I upgrade?
I just wanted to take a quick look at some technologies that aren’t too far around the corner – PCIe 3.0 and Ivy Bridge Intel chipset which will start making their appearance next year. Before I go into them, it is safe to say that with the release of Z68, any Sandy Bridge built system on H67 chipset, P67 chipset, or Z68 chipset will last you a long time. The improvements made with this current generation are the kind with which one can build a pretty decently budgeted system that could easily last 5 years. I currently have a system built around older technology that is like this.
I run a Q6600 with 8 GB RAM (upgraded from 4 originally) and an EVGA 8800GT. There isn’t a game out there that I am unable to play – though I tend to stick to games like Starcraft 2, World of Warcraft (not so much these days), and soon to be Diablo 3. They are certainly more forgiving on graphics than Crysis 2 for example, but I use them to show that a system can be built with value to play even brand new games 4-5 years down the road (I built this in early 2007). So all that being said, if you are ready and want to build a new gaming system right now, then you shouldn’t wait potentially 6-8 months for the next iteration.
The current PCIe version is 2.0, or 2.1 on some graphics cards. The PCIe 2.1 cards are simply cards which are primarily PCIe 2.0 compatible, but have some capabilities which will be usable when PCIe 3.0 finally comes out. Now for the techy part: Currently PCIe 2.0 provides 4 Gbps (Gigabits per second), or 500 MB/s per channel per direction (500 Megabytes up and 500 down -> 8 bits = 1 byte). On a board which provides a 16x (16 channels) PCIe 2.0 slot (all the boards I consider have this), you get 16 GB/s full bandwidth. PCIe 3.0 will provide 8 Gbps, or 1 MB/s per channel per direction. This doubles the information bandwidth at 32 GB/s full bandwidth. Needless to say, driving double the information is likely to lead to some pretty awesome graphics architecture.
The reason I talk about PCIe 3.0 right now is that we are likely to start seeing motherboards released over the next 6 months which provide PCIe 3.0 slots. Here is the very important key to understand: PCIe 3.0 is only going to work with an Ivy Bridge CPU. The Sandy Bridge CPUs do not interface with the PCIe 3.0 bandwidth. So you wouldn’t be able to take advantage of that until you have an Ivy Bridge CPU loaded in the system – not to mention you would also need a PCIe 3.0 video card which do not exist yet either.
IF a Z68 motherboard were to be developed with PCIe 3.0 capabilites, AND the Z68 chipset is confirmed to support the new Ivy Bridge Intel architecture, AND the board tests better than my current recommendation in the Mid Range Build list. One such board which could fill that slot is the ASRock Fatal1ty Z68 Professional Gen3 – judging from the press release, it appears that the board may supply 16x/16x PCIe 3.0 SLI/Crossfire. That sort of board is likely going to run on the expensive side. I will be keeping an eye on these developments and will post new recommendations as they arise.
Until then, Ivy Bridge looks to make its appearance sometime early/mid 2012, which means we won’t see any serious implementation of PCIe 3.0 until then as well. If you are looking to upgrade, and you want to do so now then I would say don’t hesitate!
