I finally took the plunge, and revamped my rig.
The major changes:
CPU
Intel Core 2 Duo E7400 @ 2.8GHz -> Intel Core i5 2500k @ 3.3~4.2 stock voltage, air cooling; overclocks like a beast, without necessarily becoming too hot. Planning on adding a CoolerMaster Hyper 212 Evo after the annoying CNY break (puts most price-competitive r[e]tailers on hold)
Impact: It’s a new CPU. More specifically, it’s an Core i5. The best Core i5 out there. Doesn’t get much better than this. Everything that’s CPU-related has pretty much been boosted like a turbocharger strapped onto a nitrous oxide canister…on an engine with wheels. Really. It’s that damned noticeable.
All kidding aside, it did boost CPU intensive tasks immensely. A quick video conversion (RMVB to M4V) of a 34-minute (480×360 resolution) RMVB file (with Handbrake 0.9.5) took about 4 minutes (didn’t time it head-to-toe but it was around that range), reading from and outputting to the same physical drive. The exact same setup with my C2D E7400 took more like 15 minutes, I can’t remember too accurately. The RAM probably helped/hindered respectively, but I’d say the new core did damned well, especially considering I left it to 3.3GHz (stock clocks) and didn’t yet install LucidLogix Virtu. I can only imagine what would happen if I used Intel’s QuickSync on the Z68 board to speed it up.
Motherboard
Abit I-45CV (S775) / Gigabyte G41M-ES2L (S775; partly faulty, DIMM slot 2 doesn’t work) -> Asus P8Z68-V LX (S1155)
Impact: apart from the future-proofing and new RAM compatibility? The audio chipset, I guess: a Realtek ALC 887. New audio chip with modern functions. Finally got the ability to have multiple discrete outputs. Oddly enough, I lost the ability to easily have a single input, multiple output setup, which means I have to switch between output devices if I want a different arrangement of input/output (E.g. VLC [input] to headphones [headphone/amped output] AND speakers [line-out / unamped output]). I guess I’ll just have to learn the new system.
Oh, SATA 6Gbps and USB3.0 ports, two of each. Sadly the USB3 ports are at the rear, so until I find an expansion header for the front or some compatible, high-quality cables, I’m stuck with USB2. With the recent fiasco over HDD pricing due to the flooding in Thailand last October (2011), I held off considering purchasing a new drive to take advantage of the SATA6Gbps port. On that note, SSDs are dropping in price, but still quite costly. I’d go with a proper WD VelociRaptor instead. Those seem to not move much in either direction, price-wise.
RAM
Apacer DDR2 667 2GB x2 [4GB total] -> Kingston HyperX Genesis DDR3 1600 4GB x2 [8GB total]
Impact: things load quite noticeably faster now. Although it may be partly due to the fresh install of Windows I had to do*, I do believe the RAM upgrade helped the most (Hey, it’s value-RAM one generation ago to high-performance current-generation RAM, it damn well better!)

That’s about all the important features. I got an AeroCool VS-9 case, with a side window and a heck of a lot of meshing (top…bottom…front). No positive/negative pressure ventilation setup for me, just simple push/pull where air is needed: the CPU, GPU, and in-between the HDDs. I swear, the damn case is just one steel and aluminum frame with mesh covers more than an actual case, but it makes for a really good airflow-optimized case. (space for 3x 140mm fans in the front, 2 at the top, 2 at the bottom, in addition to the existing 120mm exhaust vent). Shame the cable management isn’t half as competent. I suppose my PSU’s thick cabling and sleeving compounded the issue.

Upcoming
I plan on dropping a brand-new GPU in there to go with the near-complete overhaul. Currently looking at the Sapphire HD 6850 Vapor-X/TOXIC, Sapphire HD 6870, and probably the Asus HD 6850 DirectCU, all up to a max budget of 650. No point going higher as it wouldn’t add future-proofing. Not on a 19″ 1366×768 max reso monitor anyway.
