Weekend Open Forum: Your next PC upgrade

I want to do a new build come summer, but it's hard to justify atm =/ . If I can't get around to it this year, I definitely plan on getting myself an SSD, new video card be it either Radeon 7850/70 or 660ti and possibly a Corsair Hydro Series Cooler.

I am playing civilization 5 the system below:
Intel Pentium 4 Processor 2.80 GHz, 512K Cache, 533 MHz FSB, 2GB RAM, 80 gig segate IDE hard drive, HIS HD 4670 IceQ Native HDMI 1GB (128bit) DDR3 AGP, 24 inch Samsung 1080P Monitor, HP gaming mouse, backlit keyboard.

I shouild see a large increase in performance with Civ 5 if I use an AMD FX 4100 series processor, AMD 2950 , 8 gig ram, two 60 GB ssd (one system, one data)? Will I care if I us an Intel processor instead given the performance level of my current system?

If I have a 1080p monitor, how can I tell if it will support higher resolutions? Should I care to play games above 1080P or is 1080P good enough for a 24" LCD monitor.

I'd love to get a SSD but at the current price point I will settle for a new 6Gb/s SATA HD. I am currently running on an older 3 Gb/s model which is approaching end-of-life. Following that I'll be making the jump from 4GB of RAM to maxing out my motherboard at 8GB.
