Please Review ~$1,800+ i7920 Build

First, the template-

APPROXIMATE PURCHASE DATE: Over next 2 weeks as parts are available so I can build over some holiday time off.

BUDGET RANGE: ~$1,800 but price is less a concern than reliable/compatible parts since I only upgrade every 2-3 years now (with 3 little kids + wife, free time is scarcity).

SYSTEM USAGE FROM MOST TO LEAST IMPORTANT: Gaming, internet, some photo editing - no movies, so blue ray not an issue

PARTS NOT REQUIRED: As indicated in list below

PREFERRED WEBSITE(S) FOR PARTS: newegg.com, but open to other suggestions if from reliable company

COUNTRY OF ORIGIN: Florida/U.S.A.

PARTS PREFERENCES: i7 920 build, ASUS/EVGA/Gigabyte MB (based on prior positive experiences)

OVERCLOCKING: Yes, but not much luck last time around with ASAS Striker - so wary

SLI OR CROSSFIRE: Yes in future, but going with single card to start

MONITOR RESOLUTION: 1600x1200 - Viewsonic P22f CRT

ADDITIONAL COMMENTS: Gaming primarily consists of RPGs (Fallout 3, Oblivion, etc.), pausable RTS (Company of Heroes, Supreme Commander, etc.) and 4x space epics (Sword of the Stars, etc.).

Existing system is an Antec P182/ASUS Striker Extreme/Q6600/2GB/2x8800GTS512 SLI which is being handed down intact to my 8 year old daughter.

Having surfed the last week through various build guides and a ton of recommendations on this forum, here is what I have put together so far (** indicates questions I have)-

[OS] plan to buy Windows 7 Home Premium (~$105)
http://www.newegg.com/Product/Prod [...] 6832116754
**Question - I do play a number of older games is it worth extra $20 for this so called "XP" compatibility mode that is only in the Professional version?

[MONITOR] already own 2004 Viewsonic 22” P225F @ 1600x1200 (~$0)
**Question - this is still good monitor so I prefer to keep it, but would I see much visual improvement by switching to similar size LCD to make it worthwhile investment?

**Question - it was too good to pass up so I bought 2 packs for a total of 8GB, however I now realize I was thinking old school dual channel, not triple channel. Hopefully, I can still use all 4 of these sticks.

[GPU] plan to buy SAPPHIRE 100282SR Radeon HD 5850 1GB 256-bit GDDR5 (~$310)
http://www.newegg.com/Product/Prod [...] -_-Product

Thank you in advance for any assistance you can give me.

RAM: You should only use 3 sticks, using the 4th will take you out of triple channel and slow you down. Its possible the motherboard will do two dual channel pairs like a p55 motherboard would. Have to read the motherboard manual to find that out.

The Samsung F3 1TB should be cheaper and faster than the Caviar Black 1TB HDD.

Since you are in the US you should strongly consider getting an XFX graphics card due to the double lifetime warranty. Sapphires warranty is only 2 years. Right now the 5850 is the best deal and very hard to find. The only real alternates are to buy a 5870 or a pair of 5770s which in crossfire perform comparable to a 5870. ATI keeps promising more GPUs are on the way, but they have not caught up with demand yet.

For $150 you can get a 21-22inch 1680x1050 LCD. For $150-200 you can get a 1920x1080 22-24 inch LCD. Get 5ms or lower response time. If you want to be pickier than that you will need to do some research.

Hi

Just wondering if you managed to get your Viewsonic P225F working with Windows 7?? If you did, can you let me know how as I'm having a really bad time trying to get it going! Problem is I need the refresh rate to be 100+Hz (for work purposes - this is min we can aford), and the generic driver on windows 7 is stuck at a rather slow 85Hz! Any advice would be gratefully received
