Radeon HD 5800 Series
Nvidia should also be coming out with the GTX 300 series in a few months. These will be in direct competition with the HD 5800 cards, affecting prices even more. My advice: if you plan on spending more than $150 on a video card soon, don't. Wait until early 2010 for big GPU purchases.
Lucid Hyrda 200
Speaking of graphics cards, this nifty piece of technology should make GPU upgrades much more pleasant. Basically, this is a chip that can be included on motherboards that will allow you to use two very different video cards at the same time while benefitting from the performance of both. For example, you could theoretically have a Nvidia 8800 GT working in tandem with a new AMD HD 5850, getting a performance benefit otherwise not possible with either card. Due to the limitations of SLI and Crossfire, something like this is currently impossible.
Motherboards with this chip will be a bit more expensive than normal, but we'll see how the market reacts. Benchmarks should be available closer to the release in a month.

I can see these processors being even more important for the mobile community than the gaming community. With a low-power 32nm process and only two cores, the performance/battery power ratio should be amazing.
Windows 7 and Multithreading
Most benchmarking sites use Vista x64 right now, but I stumbled upon this Tech Report review that switched over to Windows 7. They seem to have discovered something that could be quite significant for gamers. It appears that modern games in Windows 7 make better use of multi-core processors than in Vista or XP. According to the authos, Scott Wasson:
"Another trend of note is the relatively poor showing of the high-frequency dual-core processors we've included the group, the Core 2 Duo E8600 and the Phenom II X2 550. This isn't a trend we've come to expect, the higher clocked dual-cores falling behind even the slower quad cores like the Core 2 Quad Q9550. We are using newer versions of both of these games, which could have better threading optimizations. I kind of doubt that's it, though. My stronger suspicions involve Windows 7 and the switch to Nvidia GPUs and graphics drivers. Somewhere along the line, something has changed that's tipped the balance in the favor of higher core counts."
I think he may be on to something here. I've read about how Windows 7 had some significant adjustments to the way it assigns threads to cores, so I'm inclined to assume Windows 7 is the culprit here. When more Windows 7 CPU benchmarks arrive, we'll know for sure.
Keep in mind that these benchmarks were run at very low resolutions with very low graphical settings. This is done in order to turn the CPU into the bottleneck. In the real world, your GPU will almost always be your bottleneck when gaming, so this will only be a serious concern when your computer gets very old. Even so, I think the find is quite interesting.
Also interesting to note is how well the $200 Core i5-750 performs in the gaming benchmarks. This little sucker combined with a HD 5850 should be a sweet spot for budget gaming performance.
Bargain Gaming Rig
This is a significant upgrade from my previous bargain gaming rig. Instead of an Athlon II we have a Phenom II, and it's an unlocked Black Edition too! On top of that, the HD 4870 will deliver a significant performance boost over the 4850, and can handle higher resolutions with ease due to the 1GB of GDDR5 RAM. The hard drive also doubled in size. For an increase of only $75 from the last build, it's a great way to go.
