Four years ago Microsoft released FSX with some incredible screen shots that turned out to be impossible to simulate with thecomputer systems that were available beck then. I stuck to FS2004 until this year when I saw a link to Jetline Systems of FlightSim.com. I saw the specs on the HellFire GTX and was amazed at the possibilities. I emailed questions to Greg Sanderson, who was very quick to respond and very helpful. I went ahead and ordered it with all the goods. Over the last couple of weeks, I've been in FSX heaven! I run add-ons like Active Sky Evolution, Ultimate Traffic 2, AES 2.08, PMDG 747, Captain Sim 757/767, and Wilco 737 & Ejets, plus a slew of sceneries. With most sliders maxed out and additional display options checked, my FPS never fall below 25 in busy areas in the U.S.and Europe. In less dense regions like Latin America, my FPS fluctuate between 100 and 200! Everything runs smoothly and I am yet to have a fatal error. No more Dell systems for me! I will stick around with Jetline Systems. I feel like I have my own fleet of airplanes given the realism provided by such a fast and smooth system!
