1. What is the resolution OP plays on
2. What OP considers comfortable FPS
3. What other settings OP considers necessary(AA, AF, etc.)
Without these questions answered all advice here is pretty much blind.
It was more of a generalized question about increased performance with a quad 3.0 over a dual 3.0 everything else was just building specs, also i said i play on Ultra with shadows on high, which means full AA/AF. I also mentioned i have a few mods and driver tweaks, i will list them, though i don't think it really has any reflection on the current topic and how its shifted.
8x AA ( in game) --- actually i checked and u have in game AA turned down to x4
For driver tweaks I have
Performance AO,
4x Transparancy Supersampling
and 16x High quality AF (in game AF off)
for mods i have
Realistic Colors and nights 1.6
Realistic water textures
Vurts flora textures (med res)
Enhanced night sky
Enhanced distant terrain
Quality map with roads
I thought about putting in Skyrim HD 2k but as was mentioned by someone else i just don't think i have the extra Vram for even the lite version, and second i think most textures in Skyrim are just fine, i only did the flora textures cause they were horrible up close. Currently i stay at or above 30 FPS for the most part and imo anything 30+ is perfect.
I still think, if sticking with my current build, that upgrading to a 3.0 quad core and Win 7 x64 would be very cheap and effective for the system and should show at least slight increased performance in Skyrim compared to it currently.
Back to coolers, i agree that the V8 is huge, i think it would fit in my case but im not sure so i may go with the V6 or the NH-D14 instead. I know its because i know nothing about water cooling, but just the thought of putting water in my system makes me shudder.
Edit- After looking over my choices in cooling and checking out some ...water cooling, it turns out the Corsair H80 is a very good cooler, very easy to install and maintenance free, its already pre-filled and never needs refilling, also its smaller than most air coolers so it shouldn't get in the way of many other parts. I may jump into liquid cpu cooling after all.
