In case you didn't see this question in the other thread: Does anyone know if I can use an Appian Jeronimo Pro Quad card and a 3 yr old NVDA card installed next to it in my machine with two monitors hooked up to the Appian and one hooked up to the NVDA under Win 98 SE? An unusual question. When I recently switched to RealTick it didn't like the Appian Win 98 driver which disabled some functions and caused it to lock up. And when I installed Win XP Pro on a new 120 gig 8mb buffer WDC hard drive my whole system ran much slower and now my data feed really sucks. I'm going to upgrade my 500 mhz P3 processor and mainboard but in the meantime just wondering if this setup would work. And wondering if RealTick would just refer to the NVDA driver. Too complicated. But what it is. The other thing is I'm stuck with a dial up connection here for now so that's part of the problem too. Everything worked fine until I switched to RealTick and Win XP Pro. Also does anyone have any suggestions as far as good mainboard/processor combos that work well with multimonitors? I've taken note of the P4 probs with multimonitors K_DTU in several of your posts. Thanks, guys.
