The 2xx,3xx,4xx,5xx, and soon to be 6xx are better then the higher number series, don't ask me as to why they did this but they did...
My specs are as follows:
Windows XP Professional(64bit) SP2, AMD Phenom II X4 970 3.5GHz 8.0MB Total Cache, 8GBs of Kingston Hyper X Blue DDR3 1600mhz Dual Channel, MSI 870A-G55 (Expandable to 16GB of Ram) SATA III and USB 3.0 support, Nvidia PNY GTS 450 1GB, 500W PSU, Thermaltake V4 Black Edition Gaming Chassis. Two 1TB Seagate Momentous 7200RPM, One 1TB External Western Digital My Book Essential.
Now I suspect that the GTS 250 will behave almost on par with my GTS 450, but you may have to turn some sliders down a bit in TS2010 to run it where you don't get any lag, which I can barely tell the difference with some sliders notched down 1 or 2 notches so it isn't a real problem graphically for me, others people of course will have there opinions.
But you very well maybe able to run it at max without an issue which isn't shocking because I used to be able to run 06 with almost max settings on an old 512MB AGP graphics card with a weak processor...
If I had tried that with TS2010...yea right my computer would have rolled over and died and gave me the middle finger in the process.:hehe:
