That depends on your purpose really. Intel is the fastest right now and their top end will probably always be the fastest by some margin. However, you buy that processor, and the only upgrade you'll be able to go to will be hideously expensive, and then they'll release a new socket so the next upgrade after that you need to buy a new mobo as well.
My 1100 is top of the line for AMD right now, I got it oc'd to 4.2GHz easy enough, it was cheap, and in a few months when Bulldozer finally gets released I'll have another affordable upgrade ready for me that will also be readily overclockable.
Intel is for people who have money to burn, or who aren't interested in upgrading components and just buy new PCs instead.
This money to burn argument has gotten old for me. Yes, AMD has some nice bang for buck chips (Phenom II 955/965) but the 1100T is not one of them. The 1100T is a $190 chip...the 2500K is a $200-$220 chip at most online places. I got mine at Microcenter for $180 and another $40 off the motherboard. Fry's had the chip for $150 just recently. Sure, not everyone has a MC or Fry's store, but it just to show a point:
the price difference isn't very big, but the 2500K pounds the 1100T when it comes to games.
There isn't a single AMD chip right now that can touch it (in games) and I'm not so sure Bulldozer even can at this point. I had high hopes for AMD this year, but the delays are just shocking to say the least. And if it does turn up to be something to at least match it, Ivy Bridge (die shrink) isn't far off to put it behind again. Right now, the 2500K is quite the bang for buck and you can thank it for dropping those Phenom II X4 chips to the price levels that they are now.
The thing about the 2500K though is how well and easy it is to overclock it. I've built hundreds of PCs in the past (mostly for customers) and this is the first time I've actually felt one wouldn't need to change the CPU for 3-5 years especially if one is willing to overclock the chip. 4.6GHz+ and it simply just flies and i can't see it being a bottleneck for maybe a few generation of video cards. Software is well behind CPU hardware advancement...most games still at most utilize only two cores.
And I have the same feeling for Bulldozer as well. Get one and won't really have to upgrade for years. At the price point of the 1100T...I have to say that chip is NOT worth it. Unless Dabenguin (person who posted about it) is some die hard AMD fan that just must have something now, he/she should either wait for Bulldozer or get a 2500K if something must be had now. Or rather get something cheap like a Phenom X4 955 and an AM3+ good to go board in prep for Bulldozer....still, somewhat of a waste in the end IMO. Could've been sittin pretty with a 2500K.
MS Windows SP3 AMD Phenom 9650 Quad-Core Processor
3 GB Ram, ATI Radeon HD 4550
Thinking of changing the 4550 card but what do you guys think and what cards do you know that are good priced and good for gaming.
That's one of the weaker quads in existence that will bottleneck a lot of cards these days. I personally wouldn't even go further than a Radeon 5770/6770. The GTX 460 or Radeon 6850 at the very most.
Please be sure power supply is adequate for the video card upgrade....don't just assume it will be.
Ok, this is where I am currently at, with a DELL 8300, I bought new in 2004.
PIV 3.0ghz Dual Core
4 gigs of system ram
VisionTek ATI Radeon HD3650 1gig DDR2
Dell 2702WFP monitor, currently running 1920x1200
Where does that put me as starting?
I am thinking I really need to get a totally new system, to really run this game the right way, what do you think, and recommend?
I doubt you could even get by with the rather dated CPU, which will be the biggest problem. The Pentium 4 is a Dual-Core pretender....very very bad implementation of HyperThreading through ALL the Netburst based chips. It really is only a single core chip and I can almost guarantee it will struggle. Not many single core users have had a pleasant experience with FO3 or FNV for that matter. I would expect the same here.
The video card is more in the low-medium range.
Should invest in new PC....and look into building one yourself.
