I am currently using an I5-661 with integrated graphics, and am looking for a reasonable upgrade. I am fairly new to FSX, so I am not ready to build a new system yet. A new system should happen later in the year, but I would like to bump up this config now for a more enjoyable experience while I figure out what I want later.Current configuration:I5-661 @ 3.3Ghz stock cooler using Intel integrated graphics4GB DDR1333Two 1920x1080 monitorsWin 7 Pro 64bitI am looking to add a video card, overclock the CPU, and add an additional 4G RAM as this seems a reasonable compromise.Possible upgrades:Video: GTX560 ti, but am not sure which version. 1GB or 2GB. Other posts suggest that 2GB is needed for multi-monitors. I have 23" monitors, but would like to go somewhat larger. RAM: Would adding 4GB of DDR3 1333 make a difference?CPU: I understand that CPU speed is paramount, but I have not overclocked before. Would OC'ing this CPU be worthwhile? Any CPU cooler recommendations?Thanks for providing any critiques/comments.Kevin

That grafic card looks good. As for the RAM size I don´t really know. I´m currently using a 1 GB GTX 560 SC feeding 2 17" displays and it does use the whole GDDR. So 2 GB could come in handy for the future.The additional RAM could help you if you have lots of things running at the same time or FSX using a lot of resources (mostly 1,5 - 2 GB on my system). 8 GB will likely prevent you from running into OOM´s (But I´m also happy with my 4 GB, I never had such an error.) As the RAM is resonably cheap this days, 4 GB more won´t matter that much.For OC´ing I can only speak for the second generations core i´s. With them it´s very easy to oc (at least the k variants) but I´m not experienced with the first generation. But with decent cooling you might get arround 4 GHz out of that. That will likely be all right till your new system will be ready.

Thanks for the input.Yes the RAM is cheap enough to not give it anymore thought.I was ready to pop on a 2G GTX 560 ti when my 11 year old son said he really would like to try a setup with 3 monitors. I have been leaning away from Radeon because of the Nvidia bias and my preference to a single larger monitor.But since he uses it far more than I do, I had better do a little more homework.Kevin
