I have to say...I was reluctant at first to get the McPhat 757 UHDT set because I was still running FSX on an older PC and it would get too choppy with the Free McPhat HD textures...so I was trying to do it myself because the liveries I wanted didn't exist in the normal resolution...it has been a learning experience for sure and a lot of fun. I want to continue and I know I have a long way to go because I would like to learn how McPhat does it...OMGoogness!
I am getting a new PC (it's being delivered) and I went ahead and got the World Airliners vol3, I wanted the blue United texture along with Eastern, the 757 launch customer, so I feel it was worth it with the way these textures look and you get the BAW and USAir etc...all totally amazing!
Doing textures in the old resolution seems like a waste of time to me now...I'm going to start over but it may take me a while with the new PC to slow down enough to actually make a HD template and do textures.
Here's what I got, which will later become my media PC (I'm planning on building an overclocked PC later)
Dell XPS 8300 i7 2600 3.4ghz
windows 7
1.5tb HDD (going to add a SSD boot drive with room for FSX only)
12gb RAM
added my own pick of video card, dell does not offer...
Nvidia GTX 550 Ti 2048
What do you guy's think? this should rock fsx fairly well...?
and does anyone have the McPhat World Airliners paints? Totally awesome, I'll be getting one or two more of them.
I am so stoked

this is what I have been running FSX with...

Dell Dimension 8200 P4 2.54ghz
windows XP
2gb RAM (I think, might be 1)
Nvidia 512gb video card
