Well its not a major obvious problem but I would opt for a Western Digital > SeaGate. Every SeaGate HDD I have had has died early in its life and has caused me massive data loss. The Cavier I have in my sig I have had for 4 years and never seen a performance hit.
On a P45 chipset, DDR3 will not be significantly faster in gaming performance. 4gb of DDR2-800 ram will be fine. Don't pay extra for lower latencies, it won't matter much either.
I think Samsung makes the panels for many other monitor vendors. I suspect that they keep the best samples for themselves. A monitor is a long term purchase, it is worth stretching to get the best you can afford. Look into a quality 24" 1920x1200 unit.
@HW98: In fact I am an AMD fan, but this time lot of things got in the way like cost, heat, CPU clock speed, etc... so decided on Intel setup! However, if u think a under gudget, cool & powerful replacement is available for my above config, with AMD as core, do post it, i will check it out for sure... thanks!
@geofelt: Even I got that info, but felt that ddr2 might phase-out or become costlier than ddr3 at some point in future... so planned to stick with combo for now! thanks. will check out the 24" monitors too... if only $$$ gets adjusted ;-)
