New PC - AMD 3.0G QuadCore via Newegg.com
I had a little bit of trouble with my 4+ year old PC, and spent a few hours trying to fix things, and then just ordered a bunch of parts from www.newegg.com to build a new, faster PC.
My old computer was a Pentium 4 2.8Ghz (single core, with hyper-threading). I have a ton of hard drives in it, and that was what went wrong, all but the OS drive seemed to fail. I've got backups of all the data, so nothing was lost, and I've gotten some of the hdds to work since but, it was time to build a new fast PC. I've spend thousands recently on cameras and lenses, and it was time to let my PC catch up.
The quick description of my new pc (order Saturday, parts arrived Tuesday, and it's now built already) is:
AMD Phenom II 3.0 GHz Quad-Core - uber fast, rocks!
4 GB RAM (I've already ordered another 4GB since it was just 50 bucks)
1 x 1TB HDD for OS install/C drive
RAIDMAX case with 500 watt powersupply - N82E16811156062
EVGA 512-P3-N841-AR GeForce 8800GTS (G92) 512MB 256-bit GDDR3 PCI Express 2.0 x16 HDCP Ready SLI Supported Video Card - Retail
And finally the motherboard, that supports a bagillion USB and SATA connections:
GIGABYTE GA-MA790X-UD4P AM3/AM2+/AM2 AMD 790X ATX AMD Motherboard - Retail
The above all cost under $700. I've since added 4GB more of RAM, plus now a DVD writer, 2 more 1.5TB HDDs, and a copy of Vista 64bit which came with a free upgrade to Windows 7 64bit.
This new computer is so friggin fast compared to my 4+ year old PC it is amazing.
