Help choosing cpu for HTPC

Looking to replace an e8400 based system (Mobo died) that will be used as a front end box for blu-ray discs (not mkv rips), other media and occasional gaming including pcsx2 (I might throw CoD on there down the road as I did enjoy WaW and it would be fun to play on the big screen). I have a dedicated gaming/workhorse i5-3570k/nvidia 660ti. But I would like the htpc to last 3-5 years until 4k becomes mainstream when I’ll upgrade my 720p projector and build a new box or demote my current desktop to htpc duties.

I have an old radeon 4870 512mb card and can’t decide between the following cpus.

A6-5400k super cheap and potential to leave out the 4870 and save power/noise

Pentium 2120 ivy bridge
Might be nice having the same mobo socket as my current desktop for future troubleshooting, but I’m concerned about ivy bridge’s troubles with frame loss on playback. Would this even apply if I’m using a discrete card?

Pentium 3220
haswell avoids the above issue at the cost of not being interchangeable with my current desktop

A6-6400k same as 5400k but a little nicer

Athlon x4 750k more cpu for the buck when paired with the 4870 which is more powerfull than any of the apu’s. I’d undervolt the cpu to put it more in line with a 65w tdp to save power/heat

A8-6400k this might stretch the budget. Though I figure that by using this instead of the 750k/4870 combo, realistically I might save enough power over the 3 years to justify the extra $30 or so.

A10-5800k/6800k these would stretch the budget. But would be the best performance without using the discrete card. Is there enough difference to justify the added cost over the a8-6400k though?

The intel build would be a little quieter and use less power compared with the Athlon x4 750k, but how would performance compare? If one of the apus is plenty powerful to run emulator games (especially PCSX2) then I’d lean towards that because of the savings in power consumption and noise. Cost is a big concern cause I’d rather spend more on a nicer htpc case (Silverstone gd05 vs nmediapc 1000b). However I also want to be sure that performance of the new build is considerably better than my old e8400 setup. Cause if it’s not I could just buy another mobo and cheap sound card with 5.1 analogue outputs for way less money. Also, anyone know of a good website with lots of htpc based benchmarks? tomshardware is awsome but it is a bit one dimensional.

Thanks

Of course there's the AMD Athlon x2 370k. It's roughly the same price as the g1610 and has roughly equal performance at stock, but can easily be overclocked to outperform the Celeron. The biggest upside is, AMD's fm2 motherboards have a lot more features than the Intel motherboards for the price. Especially for HTPC's. It's something to think about.

AMD's apus are perfect for what you're looking for. Even an A4 would work. But I think you should look at one of the non-K model apus if you're concerned with heat/power. A8-5500, A8-6500, A10-5700, and A10-6700 are all 65w but share the same graphics as their more popular brothers.

If you don't want to spend the extra money on those quads, the A6-5400k/6400k would be fine.

If you want to keep your 4870, get a Intel g1610.

if i go with a pentium it would be paired with my 4870.

As for the non-k models I looked at those and most seemed to be the same cost or in some cases more expensive than their k cousin-almost as if the non-k model were a locked, undervolted version for the same price. Plus I have experience with over clocking so I figured I'd just underclock the K models to match. So i figure it'd be nice to have the option to run it at full steam or hit it with the nerf bat if i get annoyed by the noise.

Seems to me that building a gaming rig is super easy. Just buy the biggest, baddest, most powerful stuff you can afford. HTPC on the other hand is a much more delicate operation-esp when on a tight budget. You want enough power to last while being cool and quiet and small..... a game of finesse if you will. Thankfully I've decided to ignore the small part.

Cheap, performance, size...... pick 2.

hmm... the celeron.... i've had a real distaste for those since i had one years ago and it was so underpowered. But looks like it would be similar in performance to my e8400 and at $43 on amazon that's looking quite tempting. Course i plan to wait for black friday deals. So who knows what prices will do then.
