I think this is the place to post this thread, but not sure....
Here's current specs:
Windows XP - 32bit
Processor: AMD Athlon II X4 630 Propus 2.8GHz Socket AM3 95W Quad-Core Processor Ram: 4GB DDR3 1600
Mobo: ASUS M4A785TD-V EVO AM3 AMD 785G HDMI ATX AMD Motherboard
Video Card: PNY RVCGGTX4601XXB GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
Power Supply: 850Watt... Don't know brand offhand
Potential Upgrades:
I'd like to upgrade to Windows 7, either 32bit or 64bit. I'd also put in another 2gb to 4gb of ram if 64bit. I MAY add another video card for SLI.
Questions??
1) Should I upgrade to Windows 7?
2) 32bit or 64bit?
3) Does it work well with PR? Your experience with PR under that particular OS?
Thanks in advance!
