Finally getting around to testing these guys (I bought 4 Modders) and I'm definitely happy with them for MAME purposes. All i5-2500 cpus, but I also noticed they're all 8GB of RAM, which I appreciate, but didn't pay for! Uh... thanks for the free upgrade, TKW?
I didn't know until this morning, when I started tinkering, that the base i5-2500 only has "HD 2000" graphics on-board (the 2500K that I've been running for years has HD 3000). I was having trouble running blitz, ttt, gauntleg, etc. at 100%, with HLSL, at the native 1280x1024 resolution of my Dell 1908fp monitor...
Fortunately, the quick and easy solution was to run at lower desktop resolution (1024x768) At that point the i5-2500 is definitely able to keep up 100% speed, with the tougher single-monitor games
with HLSL running, and the games look fantastic. I imagine it'll still choke on multi-monitor games, but I haven't played with that yet.
In other news, we just put down a deposit on a new rental in Harrison, NJ! No more living in Manhattan! No more alleyway builds! I will have SPAAAAACE! Many projects already in the queue, if the 4 Modders didn't already give that away...
