I have OC'd my 1055T with stock cooling to over 4 GHz without breaking 35 degrees at idle. This did however make my system unstable and made it have problems when booting windows and during benchmark tests. I brought it down to 3.8 GHz and now it's much more stable (from what I can tell- i'm too nervous to run the benchmarks again) and won't break 37 when doing internet apps and basic multitasking. It had a WEI of 7.6 at the 4.2 GHz. My question about this is, is the unstability from overloaded PSU (i've only got a 460W) or CPU? I know it's not the temps because i've been monitoring them closely.
In terms of graphics, i've done some more looking and decided that my top budget is probably close to $120 limiting me to the HD5750 at regular price and (maybe) something like the HD5770 or 5850 if I can get it on sale for cheap enough. I've seen many high-end graphics cards on shell shocker before, maybe I will get lucky? Of course, there's all this talk about the northern and souther islands GPU's, so i have to ask: 1) when will they be out, 2) how much are they going to cost, and 3) will it be worth whatever extra cost there is to get a 6000 or 7000 series GPU? Of course, the prices of the 5000 series will fall when they come out, so that has to be considered.
I must remind myself that there's no point of getting a better graphics card until I get a better monitor as my onboard hd 4250 is already putting out much more than my 6-year old monitor can display, so it'll take me quite a while to save up for all of these things. I can always get a graphics card and hope that I get a monitor for christmas.
